On test at the moment, I can choose to retrieve my username by entering my email address on the "forgot username page", or my password by entering my username and email address on the "forgot password" page...

It seems to me like it would be simpler to just have one page which sends one email with both the username and a link to reset the password, since you can get both of those with just the email address anyway. Is it really so common for people to forget their username but remember their password that they need to be separate?
