Pros:
Easy To Read
Easy To Navigate
Good amount of topics for your members
I have a few suggestions:
I notice your banner and menu is really the most intriguing part of the forum. You have your wilderness theme, link colours + hover and it all goes well with the banner's colours. But all of a sudden, the theme sort of disappears into a bleak gray. Perhaps try modifying the theme a bit to fit the entire page... possibly a light green theme? If you need help choosing a colour scheme, http://kuler.adobe.com helps a lot.
Your forum is looking good. It's well in shape and simplicity and nothing stands out that takes away from the forum. Good work.
There aren't any TERRIBLE problems with your forum, so that's good. The two things i'd consider are this:
1. Increasing General Activity: I know you're working on this now, so just keep it up! Keep promoting and eventually this will improve. You've got me as a member there so I'll try and keep the place up too. I've noticed your Shoutbox isn't used very often and those kind of things make a site more interactive. So I would suggest moving to a place people can always see it, like directly integrating it into your homepage. (not just linking it in the menu)
2. The Super Moderators Group: This is empty. Empty groups don't exactly add much to a forum in general. My suggestion is to either add someone to this group, or think about removing it in the future if you think it's not really necessary!
You got a good place, though some people may not really be into camping, which is the main downside of this forum. However, it's pretty versatile in categories, so you still have a good chance of attracting typical guests. Good luck with your forum, pandaa! 🙂
