Hi bob3160,
It is just one of these online habits, and as you come to think of it computer language is just a big litany of abbreviations. Some we do not even feel any longer and are used as the actual terms.. Who is writing out html, dll, http etc. Then you start to use them yourself, FreeWheelinFrank becomes FwF, polonus becomes pol (this one was actually introduced by bob3160, if I am right), sometimes you are pointed at using the right abbreviation like Firefox is not ff but Fx, Flock apparently is short enough, wwdc is a program called Windows Worm Doors Cleaner. So everybody is at it and it is economic on the querty board.
CU@f.a.c means see you at forum avast com for instance, a sentence in eight digits. So NoScript becomes NS, Adblock Pro = ABP, RQ is RequestPolicy, yarip is an extension with the name yarip, meaning Yet Another Remove It Permanently, JIT is a javascript engine in Fx translating to Just In Time. So, bob, I am only your minor by a couple of years (61) but in using lingo I feel reversed (16). So abbreviations keep you young,
polonus aka pol aka luntrus aka Damian (aka = also known as)
