I have a few invite only sites. One I setup I have me and one other admin on. I have sent my self a invite email to make a how to video on, and after filling out the info, and the gottcha I get a error stating site is closed to registration? This was a invite sent to the email I was registering with too.
snap shot of it...

It may be a simple setting. I have had some one on another site I built state same thing. Do the email invites have a time limit? I resent a invite, but when I tried it, the "email address has been used" was stated

Any how...thanks guys!
