I too have created a Wiki for the campaign setting that I am creating and would love help! I would like to invite anyone interested in collaborating on a high fantasy, high-roleplay-intensive campaign setting to head over there and sign-up. Just comment here or leave a note on my talk page there if you're interested.
I will also need DMs who would like to help me beta test the campaign setting as well. Again, leave me a comment here or a talk page note there!http://brenham.scribblewiki.com/Main_Page
