I made a wiki and I need help getting people to go to it and getting it set up
I would suggest advertising, of course in wikis that allow advertising.
Title of post: "Help"
Since you're new here I will give you a tip that the title can be more descriptive like
Help - Getting wiki populated.
Ok do you know what wikis allow that?
Not sure, also as Mention you said you should always have a proper title post to be more descriptive and so people could understand your question, such as Help - New project started, how to set it up.
What do you think?
