Been running Linux for about 5 years, Ubuntu for three of those. I run Ubuntu on servers and desktops.
About 2 years ago I became the president of the Lexington Professional Linux Users Group. (see here http://www.lplug.org) We try to cater to those people/compnaies running Linux/Open Source Software in a Professional environment.
I recently joined the Kentucky LoCo group and I hope to be helping them out in any way I can.
