@Dju

So, these are all different platforms of sorts? I don't know the lingo so you're gonna have to dumb it down for me. Are we all on a specific one--depending on where we signed up at?

@IndignantBastard yep, it's like email. iy you have and adresse x@gmail.com, your instance is gmail.com, but you can communicate with y@hotmail.com.
Here i give the total user numbers, and top 15 per instance :)
