Hi there, I'm looking for the best way to create a userform that asks for
an Username and Password. I want to be able to add/remove a user, I know
how to do this by writing the info to a worksheet, I also know how to
write the info to a *.txt file... is it possible to write the info into a
non text *.dat file or something encrypted?
