DIB, for some reason it didn't appear on my wall?
But if it had have done my friends would have known that I was joining to argue with them, especially as other than a few MNers all of my other friends are good friends that I would go for a drink with, oh and family...
If one person on there deletes me for joining a group and deletes me then so be it, they clearly don't know me well enough if they think I would be joining such a page without a motive.
