either that or Ive totally forgotten how to do it!
Gone to registration details, went down to the nickname box and its greyed out so I cant change it. Cursor wont click anywhere in the box, I can highlight my current name but when I do and press the backspace to delete it it takes me to an error page.
Just fancied a name change as Im about to post something.....uh......a bit minging about my health 
but no way am I posting it under this name as dont want any risk whatsoever of anyone IRL having the slightest inkling as to who I am, especially as what I want to post about is just mortifying x infinity
