Mikhail pretty much got it exact.
After being a long time Slackware user, and Fluxbox being my personal favourite graphical user environment.
I have a fairly crap computer. But Fluxbox runs nice on it.
There's alot of possible customisation in Fluxbox, which is a great thing.
I mean, I wrote a script and you can select a picture for your desktop, I'm still fixing it up a bit (Pretty buggy..)
But when I've fixed it up, I'll send it into Fluxbox, as I think it's something which Flux needs
The custom menu for Fluxbox is great.
It's not very hard to understand either.
Mikhail said Gentoo is nice, which is true, the things I've noted about Gentoo lacking..
1. You need a fairly good computer to use Gentoo.
I would hate to install Gentoo, even on my computer (Which isn't *that* bad..)
I'd be here for a few months, hehe.
2. It is essential to have Web connection, not everyone does... (Well, most people do these days I spose.)
3. Also, Gentoo isn't really aimed at helping people learn Linux, it's more for the advanced Linux users.. (As far as first distros, consider RedHat, Mandrake, Debian or Slackware? In my personal opinion..)
