It is pretty stressful for us all. I think the worst thought is that some groups will go to one place and others to others. At the moment I'm thinking unless this windows thing is amazing (could happen) I'm going with yuku. I really like the groups there, the way they work. It did take a bit of getting to grips with but once you start it seems quite fun. I've made my first skin (not that I'd show you lol its a bit dodgy) but I know now I can make a place my own. Someone has posted up a way to use backgrounds (which I've yet to try) but that sounds like there is hope! I can see though if some groups go to multiply, some to google, some to another etc I'll just end up loosing some. Such a shame.
I hope we manage to get something together in another format that will intrest you all. Just got to get used to another format.
I think lots of groups will go to multiply just to keep their history so they can go back to it on there incase they don't have time to back up everything. Personally I can't get on multiply, I've managed to opne one page but never get any further, it locks up my pc so if a group is moving there I doubt I'll be able to follow.
