Ok, we are literally besieged by alts at the moment and I'm putting in new rules to help fix this.
All main characters (whichever one you play the most) are allowed a period of 1 month inactivity. If you go beyond one month without contact or posting on the forums why you arent playing, you will be assumed to have quit, and kicked.
For every level your alt is, you are allowed half the level in unplayed time, rounded down. So, if your alt is level ten, then you are allowed five days unplayed time before it's kicked. If it is level five, it is allowed two days, etc. this goes up to a maximum of two weeks until it hits 70, at which point it is allowed one month, same as your main.
If your main or alt gets kicked, you can log in and request to be invited again. In order for the toon to be reinvited, it must have leveled five more than when I kicked it. This is to stop people from simply reinviting whenever they log in, forcing them into some progression of the character, however miniscule.
If your main is kicked then reinvited, you will have lost whatever rank you had before (I mean, come on, how hard can it be to log in once a month for a while

)
Unless anyone has any serious complaints regarding this, I will be implementing the new rules 4 days from now. This will help clear the guild list of all the useless level ones (mine included, I wont pretend i'm not guilty of the neglection of alts). With luck, it will help clear the guild roster of inactives, and help give me an idea on just how many guildies we have.
Seriously. I have no idea, and it scares me

Cheers!
