I was thinking to create a discussion chatroom with the answerer of the question: https://codereview.stackexchange.com/q/259468/230104
In that case, do I need to manually create a new room? or is there an option such that I can import the answer comments to the chatroom?
@raf You can automatically import the answer comments if the comments get too long. Not before that, and not from multiple answers into the same room.
You will get a notification under the comments when that happens.
Perhaps creating a room manually would be easier, your call.
@Mast I see. The comments could get long if he put everything in a single answer.
@Mast okay.
Let me know if you need any help with that.
@Mast Is there anything I must be careful about the room name and description?

If you've not got a specific problem you can identify, or an error, this question is better suited for the Code Review Stackexchange site. Btw, in random_student(), the last line should be return Student(*result) - notice the *. That expands your list into multiple parameters which will be received by __init__. That's definitely an error you would have got but haven't shown or identified. — aneroid 21 secs ago

@ThomasWard I don't see those on the dashboard. the flag just kicks it into the CV Queue
wonder if the CV queue doesn't show them for some reason... maybe I should prod CMs to stab the system... thinks
normally I'd summon the Great and Powerful Shog but they're gone so
CVqueue is personallized
so if a user already voted on some post they don't see it in the queue
4:57 PM
I know in the past sometimes posts won't appear in the queue until ~18-20 minutes old but these are older
that may be why @SᴀᴍOnᴇᴌᴀ doesn't see it
but i'm happy to wait :)
it's in there somewhere.
sips caffeine elixir aka COFFEE
welp... so the timeline for that is ... interesting
I can see a flag from 29 minutes ago and from 15 minutes ago (QuestionRecommendClosure), but the review item was literally created a minute ago
@ThomasWard Actually the reason for closure should be authorship since they didn't write the code.
probably some SQL Scheduled job nonsense
@CaptainObvious I see this now in the CVQ
4:59 PM
@pacmaninbw i think it could be either
but made a note of that on the extra comment ;)
Sounds like a culture question, as you say. You should probably have some level of code reviews, and code has to meet a coding standard (which everyone agrees on) before it can be merged. — canton7 56 secs ago

maybe the system is being weird ;)

does that thing actually still spin? I thought that was an MSEChat only thing
i still have a link to the old blame wheel :)
lol it just pointed at Shog still xD
5:18 PM
@gunr2171 Yes, it may be, but then this may be the answer. Even though this should be solved on the social level, asking for a technical solution is not wrong. Its a similar question whether you should be enforcing code reviews or make them optional. — PMF 29 secs ago

@SimonForsberg @Mast Nomination done.
Appreciate the answer--the questioning of the rules is legitimate, and we are bending over backwards to listen to the concerns of our teammates and make rules that make sense for our team. We're also looking at every rule before enabling instead of enabling the full suite. We do code reviews, we are reviewing the standards constantly...it's just so hard to get people to care when they just plain don't, and I'm not sure how to get people to care. I guess we'll just have to be super thorough looking for those #pragma disables if we can't catch that automatically. — erikjw just now

Nope :p
@Peilonrayz but you can by replying to your previous message

@Peilonrayz well, not like that, but by manually replying to your own message

you can also use the link-preview obtained by hovering over that link and just type it out
