I've registered before this with a username "Vincent Chow", and went to login at the tools page. No matter how many times I try, it won't let me in. I suspect that it is because of the space on my username, and registered with a new username, VincentC. It works by then.
Maybe remind members about this issue so they won't register username with a space to avoid such error? Sorry if there is already a reminder on it, just that I didn't notice it.
Whoops, you are correct, we are pretty strict when it comes to sanitizing input, guess I'll have to allow whitespaces for usernames! Thanks for the report, I'll fix this tonight.
