A support for GC and GEM will be great, that way we don't have to force all guild members to choose this addon over the other. That's what I love with most Ace/Ace2-based addons, they provide support for other similar addons.
Just when we FINALLY got a functional web-wased calendar sign up system developed for our guild, you go and start development on this puppy.
We also used GC for quite some time and had several, several, several syncing issues. This lead to arguements over who signed up and didnt sign up, people constantly complaining about the raids not showing for them, old version backwards compatability, the BLOAT (my biggest bitch), the list goes on.
Eventually, we gave up on the in-game type systems, and reverted to RaidSpace (yes believe it or not, RS is still around). It worked great back-in-the-day, but without a calendar linked to it, we were forced to have Forum-based sign up links, which was very management intensive on our GM to keep updated week to week.
FINALLY we have guild calendar system, but no in-game easy sync system like I see being developed here!! <damns Kael again>
I can't wait to see what becomes of this mod. You sir, are my hero and arch-enemy. <waves with evil grin>
