help me pick a flavor of linux

I recently obtained a win98 laptop and feel like using it to play around with Linux. I need something rather light on resouces and with a good support community for if/when I need help. What do you suggest?

EVERY distro MUST have ALL sources available for the distributed packages. Even Ubuntu and OpenSuSE.
If not, they'd have problem with the licenses of ~90 of the distributed software.
