okay, be gentle with me... I VI'd my first Perl script one whole week ago :D.
I'm tryin' to brew my own web based e-mail, more for the satisfaction and learning than the necessity (so i'm tryin to steer clear of too many CPAN modules and such, except for cgi.pm).
And since I would like it to actually be usable on, say, a public computer (gee... web based e-mail on a public computer?), I get the feeling that passing the username/pass as plaintext additions to the URL is probably not such a good idea :D.
