I personally Love D20 Modern and the only thing keeping me from putting up a fan site, is the fact that I have been spending my time puting my new campaign together.
I am thinking about putting up a campaign site, however, which will probably become a full fledged fan site knowing me.
I better watch it tho, the last time I designed and put up a fan site for an rpg it got bigger than I could handle and I had to hand it over to a friend to take care of for me (Community: 3E was my site for about the first year and a half).
Hmmm.... D20 Modern needs its own C:3e doesn't it?
If I set up a site, would anyone be interested in writting for it?
