Droid Engineer Archive

My wife is a droid engineer, but she pretty much makes them because they are cute . The problem here is that she has no clue what most of them do. Our guild wants a guide to put up on our guild web site, but she is still not clear on what most of the droids do, as she is still in the power skilling phase of the profession. So, my question for you hard and dedicated crafters is, do you know of a web site or a post that gives a run down on all the different droids? Any info on this would be great, and thanks in advanced!

ps. Btw, don't get her wrong, she isn't lazy. She is just new to all of this and dosn't know that there are places like this to get the info
