Thanks to everyone that replied (didn't get your e-mail again, CBFalconer); I'll try out what you've told me as soon as I'm able, and I'll post what I learn.
Thanks again. :)
[P.S. You may have noticed I sent two slightly different messages to the list; the first with a good PGP signature, the other with a bad one. Ignore the one with the GOOD signature--my blood was low on caffeine when I wrote that, and wasn't thinking too straight.
The one with the bad signature came to be when I edited the first one; obviously with more caffeine, but still not enough to remember that the signatures wouldn't match.]
