I don't want to litter my later code with $_SESSION['name'], basically.

I'm still used to the old register_globals being "ON" so I basically
import the variables I want to use from there they should come from, and
add scrubbing after the logic is right.
I'll be wiping the database and starting fresh from my SQL script after
that, so an SQL injection over the next couple days won't do much.

Magic quotes is on.
I'll add more scrubbing later.

The SQL is correct, and works just fine.

No, thank you.
I don't trust browsers to cache or not cache style sheets correctly, nor
do I feel the need for the extra HTTP connection to get the style sheet.

Again, I don't care about short open tags not being ON on your server.
They're on for mine, and always will be, and this code is not intended to
ever be ported anywhere.
The semi-colon is optional -- That is a documented feature.
