Before you ask, I searched! http://dallaspua.com/forum/viewtopic.php?t=18&highlight=irc
I work in a lage Dallas-based Data Center. Traffic from all employees is monitored (that's actually part of my job) so I tend to shy away from surfing things of personal interest at work (even though I have soooooooooooooo much spare time to.)
That post suggesting a #dpua channel is like a year old, but I'd be interested in getting it going. IRC traffic is the easiest type of traffic for me to encrypt...so no one at work would be the wiser. Plus, it'd help getting people comfortable with the community, I'd hope. Any thoughts on trying again?
