Guild Event Calendar Addon

[Yak]

Hey there, I've been playing Rift for about two months now and find myself in need of an event manager. Mainly it needs to be able to provide an interface for guildies to accept/tentative/decline event invitations for events created by other players. Essentially the calendar system that was implemented in WoW.

I have some programming experience, the Lua manual and the (apparently slightly outdated) API Bible and am ready to get cracking. However, this would be my first add on project...I looked though the API Bible and am not sure if this will work...?

Does Rift use an Add on channel to send/receive add on data between players..? That would be the one thing I need to make this work and just am not sure if its there yet. Any help with this would be appreciated! Thanks in advance.
