Change username

How do I change my username.

You can't... but I can. What would you like to change it to?

I am not sure which username or password I used in the past. These used to be filled in automatically for me but I have changed the settings on my pc and this does not work any longer.
The only way that I can use the site now is by entering details in 'forgot my password' each time I use the site.
