I guess that I always figured if Aitch wanted to close down the site/ forum, there's better ways to do it than just let it die a slow, painful death. Site hosting and domain registry cost money, so if it's time to let the site go the best way to do it is by cancelling the subscriptions. I don't want to speak for her, but I would guess that Aitch doesn't want to shut the site down, she just has more important things to do with her time these days.
Does that then mean that we need to find somewhere else to call our "home"? If she does want to close it, then yes, in the long-term we do need somewhere else.
