All of the above links are a great place to start exploring Wikia. If you get stuck or have a question you can't find the answer to -- please contact us here. But most importantly, have fun! :) Happy editing!
It can be difficult to get people to your wiki, but the best tipis for you to start by creating articles about your topic. Hopefully they will be picked up by search engines, and the people interested in the same topic will come to the wiki. And maybe some of those will start writing too!
You can also promote your wiki by looking for people who share your interest, and letting them know about the site, For example, you could go to a forum and get involved there, and maybe have a link in your signature back to the wiki (if the forum allows that)
There's more on promoting your wiki here, and a webinar about SEO here. Hopefully those will help too. Good luck!
