I just looked at what the site looks like for a new user:

If a new poster doesn't ask about Mathematica, or doesn't format their post at all and doesn't care that it looks completely unreadable, then I think they really deserve very little sympathy, and definitely don't deserve an answer until they put in the effort to format their post.

It's not right that someone else does it for them and many people don't learn how to do it even after 4-5 posts.

I don't downvote much in general, but I think that's what I'm going to do for cases like that.

How much clearer can you make these instructions?

I don't understand why this got 7 upvotes, it's a trivial mistake: mathematica.stackexchange.com/q/129732/12

I voted to close, but after I saw the number of upvotes increasing, I thought it's better to write an answer ... maybe people get confused.

But I can't see how someone thought that the only way to work with LibraryLink is to copy 8000 lines of C code into a Mathematica string in a notebook, when the documentation clearly shows how to compile a file ...

@VitaliyKaurov That's pretty cool

@xavier When you use the "Share" button to get the link to a post then it appends your user ID after the post ID. StackExchange can use this to keep track of how much traffic a particular user brings in, f.e. there is a badge for users who have directed a certain number of visitors to a particular question.

@JohnFultz I know you can't tell us what's coming in Mathematica, so I just wanted to say: I watched your 2015 (last year's) WTC talk on YouTube, and saw the user-customizable auto-completion where we could control how auto-completion works with our own functions. I am very much looking forward to this feature. I hope this feature is still being planned.

@Szabolcs see this example (Github) in GitLink for how to hint completions for filenames (and directory names is equally easy...the codes are documented in that file). It's not pretty, and it's not documented, but it will continue to work because we have a lot of internal stuff that relies on this.

@JohnFultz Thanks! This is excellent. In SystemFiles/Kernel/Packages/NDSolve/FEM.m I found how to complete strings. The only missing piece that I wanted to use now is how to complete strings within a list, e.g. try ExampleData[{"NetworkGraph", "Jazz... and it will complete "JazzMusicians". This is happening not at the first level in ExampleData[...] but within a list.
