Dear All:
Well, I don't know what happened. But I can guess. So far, the only reasons I saw this happen to other communities were: explicit sexual contents or violent contents. Once you get that message I doubt you can recover the group. That's why it is so important to keep a back up group. A friend and I manage an MSN group, and as a preventive measure, we keep all addys from our members...if something happens to our group, then we know where to find them.
You will be OK. Most probable thing is that someone report something to MSN. I am sorry. But some people have too much free time in their hands.
Now, cheer up...and try to smile. Nobody died, right?
We will be OK.
Later,
Teté
