I don't think you can't change it now. You have to kill it off and start over.

when registering, I rarely disclose all info.....
*I tend to list my state only....
*Freq will put my B/D off by one day ( I always go off the same direction in case I ever have to figure it out) ( such as , if my bb'day is the 3rd I put the 2nd)
*I never use a phone #.... if it REQ u to list one.. I again offset it by one number....I've been known to lsit my ex's phone # ( I didnt mind if he got on some cold callers list... heheh)
* I always use a "trash" email box until I knwo I want to communicate with someone... I can always chg it later
* I never list my " mothers maiden name".... I use my GRAND MOTHERS maiden name
* when it asks for ur childhood best friends name... I always use her MIDDLE name

I can get a little paranoid I suppose... but that me.
