I installed the latest 1.7. I went to register. My Vortex e-mail has a + symbol in it so I keep all my spam under control (forums+vortex@...). Gmail even suggests using it so you can tell where stuff came from. It's also a valid part of any e-mail address....
So I couldn't even register to report this. I ended up using FireBug to edit the HTML on the registration page to add back in the + and continue on registering, which it let me without any problems.
So 2 bugs.
1) + is a valid e-mail address character
2) You really should revalidate everything before registering. The 'readonly' flag only works so well with people that have Firebug.
