The Group invite doesn't work properly.
1) No e-mail is sent to the user so there's no indication that they've been invited.
2) I've tried using Name instead of username, this doesn't work
3) I've tried using e-mail but they also don't work, even though I checked the settings in the system to make sure both e-mail and name were selected in the configuration.
4) I can't find any place where I can see when I've been invited to a group so there is no way for a user to know that they've been invited.

Besides inviting users of the system, if I supply an e-mail, I also want to be able to invite non-users of the system, so they will join the site. I've added the CB Invites functionality but it's not integrated with Groups and it is very basic. I tried another invite module with more functionality but it crashed. Any suggestions?

I change the default to E-mail only.

Thank you, that solved several of my problems. The system now sends an e-mails to the invitee if I use either e-mail address or if I use their username. This was the most important.

It still doesn't work if I use their actual Name.

Since the e-mail is now working I can tell when I've been invited to a group. So that solves that problem, although I think there is still no where in the system that I actually see which groups I've been invited to, although this is now less important.

The problem is you can only use one or the other. If I select username, it works, if I select name it works. but if I select name and username, only username works.

I think for now, I'm better off with name. But it probably should find both.
