something like home page that highlights members and content the same way yelp does would be a good features. Just some emphasis what the community is about!
Apart from the domain of your site and titles of posts.
Thats only thing that gives you a bit of branding about the community
The email we get for the digest gives you a very quick over view
what the community is about and it high lights best members posts.
That idea can be taken further!
At moment I have wordpress blog that can highlight members top topic posts
but wordpress is static.
This is problem with nearly all current forums. They always have a static home page
with content posted by date. That doesn’t reflect the current community
Mums net does quite a good job of starting talks on it’s home page
and inviting people to take part in conversation on the forums
