I have an account on this website but not using it for a couple months made me forgot my username... I only remember my password! Is this anyway I can find out what my username is?
Perhaps search your e- mail....when yo signe up this was in effect:
* You will receive an activation email to this address
Well log into your email and there should be a search bar.
You can type in some keywords such as web2.0calc or something similar to find the activation email they would have sent you a while ago.
Unless, of course, you permanently deleted the activation email by now. But it's worth a try!
