I've been a member for several months now and enjoy reading people's posts, both technical and humourous! However I am having trouble understanding some of the anacronyms people use ( eg. ATC, IPK, FBH, HGF). I did a search and couldn't find a guide to what these and others mean, when you know you know but when you don't it's just gibberish! Can anyone shed some light as to what the most commonly used anacronyms mean?
