@hyper-neutrino If you move people's messages here, do they get notified?

@cairdcoinheringaahing I doubt the queen uses Parenting.SE :P

hyper-neutrino

@user nope. looks like the invitation is sent if and only if a user whose message was moved has permission to access the destination channel

user

Nice

hyper-neutrino

so for example, my 1 rep sock, which has write access to Sandbox, does not get notified when i move messages to the normal trash, because it can't write there

and my 20+ rep sock / chatbot gets notified for normal trash but not trashcan

@user one is a chat bot and also serves to test some things, one has 1 rep which helps me test things at exactly 1 rep

this account was actually originally a sock but my main account got deleted due to miscommunication reasons so i contacted SE support and they merged that account into this. this was originally my chatbot account lol

caird coinheringaahing

Which is why this isn't the sock that answered this :P

I'm going to make a New Sandboxed Posts account now

caird coinheringaahing

Why not just use a "New Posts" account for all?

Redwolf Programs

I kind of like the separation of tasks, but if y'all think that's a good idea I can do it

caird coinheringaahing

It does mean fewer accounts to keep track of, and fewer accounts to try to get 20 rep on

Redwolf Programs

Maybe I'll use New Posts for Main/Meta, and a separate New Sandboxed Posts

That prevents meta questions from being mixed up with sandboxed posts, for users with Feed Filter or similar

caird coinheringaahing

So, this month, Dennis is the top rep user O.o

Redwolf Programs

18:03

How about just New Posts and Sandbox Posts?

caird coinheringaahing

That works

Redwolf Programs

Those are nice succinct names that are also easy to distinguish on smaller screens where only the first words show

user

I feel separate bots for Main and Meta might be better

Redwolf Programs

It shows the site icon in the top right

Oh ok

Redwolf Programs

Should I use the current NSP profile picture, or the NMetaP one?

I kinda like the NMetaP one

@cairdcoinheringaahing interesting o.O (someone gave him a +400 bounty but that's kinda funny to see :P)

Yes, I trust this user

Redwolf Programs

Couldn't decide between "Sandboxed Posts" and "Sandbox Posts"

hyper-neutrino

ಠ_ಠ you got to the First Posts review before I could snipe it from you

caird coinheringaahing

hehe :P

Are you using Review Stalker?

Redwolf Programs

Should I use the NMetaP or NSP profile picture? The NSP one is more recognizable as sandbox related, but the NMetaP one would look nice with the NMP one and add some consistency.

hyper-neutrino

@cairdcoinheringaahing i am

caird coinheringaahing

18:22

@RedwolfPrograms If you've got Sandbox Posts, then use the NSP pfp

@hyper-neutrino I regret sharing that with you :P

hyper-neutrino

@cairdcoinheringaahing >:-)

Redwolf Programs

I like the NMetaP one though :/

hyper-neutrino

why did Sandbox Posts' post not generate a review task

i manually loaded the FP queue when i saw that get posted and i thought you sniped it but you reviewed a different post

caird coinheringaahing

@hyper-neutrino It hasn't happened yet

hyper-neutrino

does upvoting a post prevent it from being queued?

caird coinheringaahing

18:25

Usually takes ~5 and 30 mins

No

hyper-neutrino

oh 30? lol

Redwolf Programs

Sounds like I need to break into SE headquarters and get them to use New Posts code internally

hyper-neutrino

it'll probably show up the instant i go to do something else lmao

caird coinheringaahing

@hyper-neutrino Yeah, I get that. Whenever I step away from my computer, someone posts spam on MM :/

Redwolf Programs

Can we get some upvotes on this?

hyper-neutrino

18:26

then there was that one time someone posted casino spam on CGCC like 1 minute after i stepped away from my computer and i came back 20 minutes later and it wasn't gone yet

Redwolf Programs

Redwolf's Redundant Room FTW :p

Oh, Sandbox Posts' answer is in FP now

caird coinheringaahing

Isn't showing for me :/

Redwolf Programs

Maybe there should be a separate NMainP and NMetaP still

Can I get some feedback on this?

@hyper-neutrino Looks good to me--my only reaction is "I see box-drawing characters, I think QBasic"

user

@Ausername You should vote (or do some other action) just to get a badge

hyper-neutrino

is qbasic good for drawing box characters?

or does it use them in its interface or smth

DLosc

It does use them in its GUI, actually, but mainly I mean they're in its code page. Which doesn't really make a difference once the "count them as one byte anyway" rule comes in, but that's okay. It's just a nostalgia trigger.

hyper-neutrino

oh huh, that's cool. (also i see - makes sense)

yeah, i added the one-byte rule mostly to encourage submissions to use them even though any distinct characters are allowed :P

just so it looks prettier

@hyper-neutrino how can you tell? it's not obvious from his profile as I see it at least

@Neil because I saw stasoid's bounty on Hello World yesterday when i went to go answer it in Flurry lol

may I ask what the reason for the bounty was?

hyper-neutrino

it was to this answer; i think just a typical "reward existing answer"

i don't know how the language works but it looks impressive ¯\_(ツ)_/¯

I assume that the placeholders will never be next to rails pointing in the wrong direction?

it is possible that they are, but any placeholder will have at least two adjacent rails that point in the right direction

although if the space is important, since inline code doesn't have a different background in chat, not monospacing it is a good idea
