New system- new XP install- all those passwords??

About to put a new mobo in, and will no doubt copy my C: onto my external HD prior to re-installing XP (home). I've had the same install of XP now for around 4 years, and the amount of passwords/logins to forums must be enormous that the OS "remembers" for me.I've tried to standardize on the username/password combo, but sometimes is not available as an option. Is there anywhere that I could migrate this info from my saved prior XP instance into a new one?Thanks- Bruce.
