It ain't Skype (at least I don't think so).

They've been leaving to a new RP site, which when I went there for an RP that was transferring over, I had ran into a ton of spam members who had all but vanished months ago on the Guild.

Edit: Granted none of them seem 'Happy' to see me. :P
But they're around, and it ain't Skype they immigrated to (mainly).
I wouldn't be surprised though if there were skype calls going on though that I'm not getting invited to.
