I arrived here yesterday, and I am new to the StackExchange sites. What I miss is a technical tutorial about the site features. In particular, the following isssues have me confused:
The difference between an Answer and a Comment. In particular, Markdown seems to be disallowed or restricted for comments (I tried putting a blockquote in my comment, and failed). Also, editing a comment seems to be on a timer, I can edit my comments immediatly after posting, but later I cannot.
Community Wiki: What does it do?
What happens if you delete a post you've made, for example in terms of reputation, and the comments on it?
How does closing and re-opening work?
As far as I understand, some of these things can be changed (for example Markdown) by thwe moderators. When everything is more or less set up and we foresee no major changes to the site features, I think a tutorial explaning these things would be very helpful to newbies.
Also, answers to my specific questions above would be welcome.
