Anyone interested eDX is offering a free online 'into to Linux' course. It's self-paced unline all their other courses so time is no excuse. It starts and the very basics and takes you up to advanced scripting, networking functions and processes.
It used to be $800 course (classroom) if I remember correctly. I'm starting today if anyone else gets in let me know and we can meld minds.
