Having the same problems. I think the whole signup system is broken. Hopefully Chopps gets it fixed soon. /crosses fingers.
I did find a bug related to members signing up with characters that have not yet been approved (Be sure to click the "Pending characters" option in your Alerts box). This bug is fixed for future signups, and I'll be running a script that'll fix previous signups (unfortunately, it will simply mark those previous broken signups as "Confirmed Absentee").
As for your issue, sentar, which members have been experiencing this problem? (Or is the issue related to the previous issue with the multiple auto-signups).
