It's different for EQ2 (or at least was) as they had a 60 day not logged in, membership may vote a new leader in mechanism. They also had a brief window of time on a server where you had to pay to create a guild... so not a role model. But likely a cause for some confusion in respects to what SoE (and now Daybreak) will do.
See
this thread .
You might try and petition having an active player made co-leader... but sounds like the answer would be no.
You might have greater success petitioning for some officers with the ability to boot members being made.
Does someone have permission to change the guild message of the day? If so I would reform the guild with the message saying where to find the active guild (name of tag, officers for invites). If going this route, leave a mule in the inactive guild that you login during primetime for a while just to say hello and prompt people to move.
I currently have a character stuck in an inactive guild at the moment that moved. Problem is they have only given one invite contact and I am not catching that person on... I'll have to start chasing others with the tag I guess or move on.
Good luck Vinney.
