[nfbcs] Possible Computer Science Speaking Topics

Tue Mar 5 02:07:34 UTC 2013

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
