Once you’ve created a Group, you can begin inviting new members.  Click INVITE in the upper right-hand corner of your screen and choose Invite Others to Join This Community. 

When the Invite Members form opens, if the person you want to invite is new to iBelong Communities and doesn't already have a user account, enter the first and last name in the fields shown.

Then enter the member’s E-mail address and click Send Invitation. An invitation will be sent automatically to that person's E-mail address.

To see whether or not someone has responded to your invitation, click Manage  > Members. Then click on the Invited Users link.

A list will open, showing all users whom you’ve invited.  A check will appear in the box next to the people who have confirmed.  If someone has not yet confirmed, his/her checkbox will be blank.
