I created a plug-in that imports usernames from Invision Power Board to Wordpress, but the new Wordpress version 2.5.1 does not allow import of any UPPER case letter in a username, for example:
My forum name is EJRaven, in order to login I have to write ejraven (all lower cased) in order for Wordpress to recognize me.
I looked around these forums and all I see is lower cased display names also, can someone explain what happened and why this version is messing the usernames this way?
