Since GEM is too confusing, and it's only a matter of time before GC breaks because the author has already stated he/she was done work on it...
Maybe this post should have been started in the request section.. along with the several other GEM / GC requests..
I don't find GEM at all confusing, I just find it buggy s all hell. We won't trust our raid signups to it (we use phpraid on our guild website) and only use GEM for scheduling 5-man instance runs and miscellaneous stuff.
Still waiting patiently for Combine to materialize, but Kaeltan has a lot of projects.
