What help pages need to be written?
I've been working on the user help center recently - writing new help pages and improving old ones. You can see the latest changes and suggestions - even the ones that haven't been deployed to the site yet - over on GitHub.
Of course, though, I'm not going to be able to come up with everything - there will be things that need help pages that I'm not going to think of on my own. With that in mind... what help center topics would you like to see?
Feel free to leave suggestions in the answers below; I'll look through the responses and see what I can do (and I'll be updating the to-do list).
