I don't think many people would put > and < into their username, but this is what happens:
Attachment 63681
Also, if I type in test,ing (note the comma) when I tab down to the password field, it changes the username to test.
I can't imagine to many people creating a username like
test,ing or
><testing, but I thought I would make you aware of it anyway.
I've updated as well, seems to working fine with the exception of the above.
Thanks!
