[KingPin]

I like the concept Temi, I don't think I have seen a green forum to be honest.

The things I would change are....

The colour of the forum. Perhaps a dark, leafy green with a lighter green for the threads/posts.

The icons next to the forum categories. Recycling for example, you could use the recycling icon you see on tin cans, you know, the pyramid shaped arrows.

And Energy, perhaps one of them Energy saving light bulbs.

Give it a very earthy feel and a nice airy, earthy logo.

For user status you could use catchy things like 1-100 posts "Swampy" then the highest status under Super Moderator something like "Captain Green"

It's a gimmick, but they work.

Then obviously the standard SEO, title, description etc etc.
