Yeah, I'm looking now and there's not an obvious link. I clicked the online help link, and about the closest thing I can find is this topic:
support.photobucket.com/.../200724204-I-Can-t-Access-the-Email-Address-I-Signed-Up-With
As an IT professional, I can say that my experience is that online help often doesn't, and documentation is seldom written in a clear fashion for a typical user with perhaps little or no technical experience.
