This isn't exactly a problem, it's more of an inconvenience. When I login, I type my username in and then quickly type in my password. Sometimes I'm typing so fast I mess up the password and I have to retype it. The only problem is, my username has been removed as well as the password so I have to type them both in again.
It's not a major problem, but it's annoying and wastes time (it's also the only website I've seen that does it). So, if anything can be done...well, thanks!
