Biznik and "moving" communities

I apologize if this topic has already been discussed - I browsed briefly to check and didn't see anything, but I stare at a computer nearly 24/7 and my eyes are bugging out right now.

It'd be great if the Biznik system prompted for a confirmation to "move" from community to community instead of just doing it.

I set up social network profiles for people and every time I set up a Biznik one, my own profile is moved to whatever community I set up for them. When I log in, I notice that I'm in some new community that I never "moved" to (I'm guessing it goes by IP address rather than profile?)

It'd be great if that didn't happen, or if the community was associated with profile instead of IP address. I probably look like a freak having been bounced around to all these random communities!

Cheers,

Tia
