Yesterday saw the release of the D&D 4e GSL and SRD. This has promoted some chatter on the Enworld forums over whether the GSL is unfair to the consumer? and a dummies guide to the GSL , which includes: 4.
The new 4th Edition Game System License ( 4E GSL ) will be released next week according to this WotC announcement. D&D Insider, the online subscription based service for 4e has gone live, or at least its web site has.
