Hi! I'm using the Membership plugin, WP3.3 and Buddypress. Everything is up to date.
It appears that the registration form doesn't check that the email address is in a valid format, so I've had a couple of users sign up without entering an email address (the field is still required, but you can put anything you like in there).
I'm absolutely happy to add a bit of my own code to do this but thought I'd best check to see if it was something I was missing that could be corrected within the existing structure before I start making changes.
Thanks for a great plugins, by the way! I'm very happy with my subscription!
