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.
e.g.:
login as
MickeyMouse@disney.com
MyPa55word
results in a page that simply says “Error!”
Better would be:
Successful login 
or, error message: invalid username (but maybe you used an email address instead of your username?)
thanks!
