Your registration system is absolutely annoying. Enough so, I don’t really want to bother with your site anymore.
First off, I didn’t really want to register. Then I couldn’t use my standard email alias. Finally, had to wait for a 2-factor email notification, that seemed to expire with 10 minutes. Had to get it resent 3 times.
Make it simpler!
I don’t want to bother with any of this.
