You do a great job of summarizing what the site is about on the home page, so that kind of information you don’t want to repeat unless you feel it is very important. But, anything else you think visitors should know as they explore the site would be appropriate. Primarily, though, the FAQ page is answers to “Frequently Asked Questions” and can be added to as needed. I would suggest starting with the 5 or 6 most frequently asked questions, maybe one or two of the oddest questions that you feel are appropriate, and go from there. The idea is that it will help save you, and the forum, from answering many of the same questions over and over again. The bonus is that, even if your site is brand new and you make up all of the e questions/answers, it gives the impression to visitors that there is other traffic and interest in the site. It also gives an immediate impression, to those who visit but may not ask questions, that you want to help them find what they are looking for and know what they need to know.
