unable to modify account

Thought I would add a picture avatar.

However when I fill out the form, with password, email, real name [wga, bill@wargameacademy.org, Bill Thomson} I get an error stating username must be different from my user name. However at present both my username and password ARE identical [wga] as were established prior to this restriction. so I cannot get past this screen to change my password or any other account modification

Please advise.

type an alternate user name, they do not have to be the same, your modifying your account not logging in. then go to forums and on the left side of the posts ribbon (top) is a user control panel link next to (0 new messages).
