As our Canadian friend said above, it would be nice to see a theme that is used less often. It seems that you are also contemplating switching software. Do yourself a favor and stick to phpBB. Conversion is a hassle through which you probably don't want to put yourself. Your rules look pretty solid. I can't think of anything else you might wish to include. Your forum looks very balanced (i.e. you have done a pretty good job of utilizing most of the sections equally) so far. You may wish to start some discussions outside your "Let's Just Talk" forum to make sure the other forums keep up. It's important to maintain balance on a general discussion forum so that your board appeals to as broad an audience as possible. It also appears that your forum is going through a slow period; you may wish to do a couple post exchanges to make your forum appear a little more active (only three users have visited in the past forty-eight hours) to prospective members. You've done a brilliant job of laying out your forum; your index is very small and easy to navigate, but there is still plenty of room for discussion.
Overall, I would say that your forum could use a new theme and some more activity. Perhaps you should look through some other themes and step up your advertisement. It's awesome to see that you're sticking with your forum, though, Ashley. 🙂
