[nfbcs] Possible Computer Science Speaking Topics

Tue Mar 5 12:32:30 UTC 2013

Thank you Tami.

I am on that list.  Since most of the individuals on that list do not use
Red Hat Linux version 5, it is difficult to get advice on where to start.

Louis,

Welcome to Linux! Have you tried the Orca List? I've heard a bit there about
Orca with Fedora, but don't pay as much attention, I'm afraid, since I am
running Ubuntu... Ubuntu is by far the most accessible distro, although
others are catching up!

Good luck!

Tami
