I created an alt a few days ago, and am having problems sending or receiving IMs, group invites, etc. I am unable to send her a group invite from one of my other avatars so that she can be in the same group and have access the house. I rented a condo for her... but am unable to receive the group tag. I know that they're being sent, because I see the notification in e-mail. Help! : ) Thanks!
