User Invitations Timeout
Just in case anyone else has users getting errors when they rather tardily try to activate a MadCap account: the invitation sent out from Central times out after "5 days or a week roughly" (I quote from the email from Support), and slowcoaches will get a message telling them the invitation can't be found. The solution is to Reinvite the user. At least, knowing this, I can warn folk to sign up quick!
