Does anyone use Advanced OpenEvents ?

looking for a solution for werbinar registration, tracking and publications/emails…

I looked at Advanced OpenEvents which might do the job from what I read

I found some stuff on this link
and I wonder if the module is still used and will be maintained…

My 2 questions:
1 - does anybody use it sucessfully?
2 - Is there any other documentation available?

Yep, full documentation at the SuiteCRM Wiki.
