Just got the message going into the careers site:
Don't forget! You can invite 0 colleagues to create their own Careers 2.0 profiles.
I still have 5 invites remaining according to the profile invitations page.
Was this message right?
thanks for the report. These messages are denormalized, and we were accidentally notifying people on zero invites for a little while and you got one of them. Should be all fixed now.
