I think it might have something to do with browser cookies. If you've never actually logged out it seems you can keep posting, I've not paid my March subscription yet as I'm leaving it until I'm less skint, but I'm still posting too.

I went away for the same length as you, but founded myself tempted to come back because I had great times and played with some great people, but unlike you, I gave in to that temptation and to be honest, I've not been bored...I just stay away from the stuff I've found boring or do not like and I don't have to waste hours and hours playing at a time. I'd say I still enjoy it. However, there are other games out there, much newer ones and if they tickle your fancy, best of luck. Or if you've managed to give up MMORPG's together, then well done! :P
