Bug in forum login

When logging in to forum, if i use my email address (instead of my username) all i get is “error” with no feedback. Might imagine I’m not the only one to scratch my head and feel stuck on this one. Suggest providing more meaningful error messaging and/or gracefully handling the login successfully.

login as

results in a page that simply says “Error!”

Better would be:
Successful login :wink:

or, error message: invalid username (but maybe you used an email address instead of your username?)
