I added a hack and it added a option to the "Change Options" Page, i accidently did it twice and now it says signature length twice how do i take one of them out?

Remove the setting from the settinggroup table.

Thanks freddie

I opened PHPMA and it is under user registration options but i click on edit and it wont let me cahnge anything in the group, it lets me cahnge the name and things like that?

You need to edit the "setting" table I believe, not "settinggroup" :)
