For those of you using Linked In, I highly suggest the groups EA to VA, and if you're a member of IVAA, they have a group, as does IAAP, again I think you have to be a member of the organization but I'm not positive. There are also some groups specifically for open networkers, like TopLinked, LION and Invites Welcome.
And of course I'm always happy to connect with other VA's, so drop an invite to me and I"ll accept!
