The EQ Players Website and the EverQuest Forums are each offering sign-ups to beta test EverQuest: Seeds of Destruction, the 15th expansion for SOE's long-running MMORPG. The testing is described as an open beta, but the sign-up pages make it clear that they are limiting participation. The beta test begins today and is scheduled to run through October 7, with the add-on slated to launch on October 21.
