I have an paid account (vendor account actually). I am in the process of testing your solution and came across number of issues.
One of the problem is as follows:
> I have created a free account through my co-branded site.
> I have sent an invitation to newly created user
>Received an Email and new user has successfully accepted my group - that what message was saying
> I have logged back to my paid account but I still cannot see that user in my group!
Where is the problem?
Thanks for your assistance.
