Believe it or not, d20 Modern is still alive and kicking. Not only is there a Microlite20 Modern variant for those of you who’ve been following along with my trek through the microlite world, but just a few days ago a member of RPGnet going by the handle "Sesheyan" set up the d20 Modern Unlimited forums. Given the flexibility of the d20 Modern system, this should prove to be a fertile ground for ideas.
The board is set up with a sizeable number of forums, with dedicated areas for each d20 Modern spinoff product (including d20 Cyberspace, d20 Future and Future Tech, d20 Past, the Urban Arcana and d20 Dark Matter campaign guides and the Menace Manual, and so on). Additional sections have been set up for adventure and campaign creation and discussion, an introductions forum, web enhancements, SRD links, third party product reviews and a general chat area. While the number of forums might look intimidating at first, they’re clearly organized so that content is easy to find or properly place.
Registration is set to approval, but the board’s admins should get back to you soon after you apply. If you’re a d20 Modern fan looking for some active support and interaction for your game, sign up and give a shout out. I’m already on the board as "Corvus", and I hope to see you there.
