i have a problem with world community grid my name is ramza in all projects so i got them linked to my BAM account, but my name in world community grid is ramzanox (email is still same in it and password) and when i try to link that to BAM it says wrong password, and i cant change WCG name ro ramza becouse someone has already taken it

Best bet would be to change your name at the other projects to match that at WCG. Unfortunately, there's no workaround (BAM must have same username, email and password as all projects) and you will still probably have problems with WCG and BAM--it doesn't play nice.
