Just as a side note, from experience... Omit the Letter O, the number 0, the
letter I and the number 1 from any passwords you create... This causes no
end of problems when users get their password's and they still cant login
becase the mentioned letters are hard to distinguish, espicially on fonts
such as verdana, arial etc...
I would probably use alphabet =
"ABCDEFGHJKLMNPQRSTUVWXYZ23456789abcdefghjkmnpqrstuvwxyz" to get harder to
guess passwords... This depends though on how secure you wish to make your
site...
Anyone else have any input on this issue?

Javier
