I've been reading a couple weeks in here... And most of the abbrviations I've found basic... ROB = Rites of Battle... TEP, IH, etc... However quite often I see the abbreviation RAW and haven't been able to figure out what it stands for... Is there a thread somewhere that has a list of all the common abbreviations or anything like that available? Not asking for a repost of it, just a link to the thread would be welcome.
Thanks
RAW = Rules As Written, it's a common abbreviation on the Interwebz about RPGs 
I don't think there's a glossary of sort. Could prove useful ,though, you're right 
Ahh... AKA a google search would have found it.. lol
So this is the list I could put together - trying to keep it the books and PDFs from FFG at this point so didn't include any "unofficial" supplements, not sure if I'm missing anything... And of course, if I have any abbreviations different from what has become common usage, that can be fixed...
RAW - Rules as Written
DH - Dark Heresy
IH - Inquisitor's Handbook
DDG - Disciples of the Dark Gods
CA - Creatures Anathema
TRH - The Radical's Handbook
BOM - Blood of Martyrs
Asc - Ascension
PTU - Purge the Unclean
TF - Tattered Fates
DC - Damned Cities
DS - Dead Stars
RT - Rogue Trader
LOTE - Lure of the Expanse
ITS - Into the Storm
EOTA - Edge of the Abyss
BK - Battlefleet Koronus
FB - Forsaken Bounty

FS - Final Sanction
OE - Oblivion's Edge

only thing I would say is if you are gonna have RAW you should have RAI as well (rules as intended). this is often the counter argument to rules as written in cases where things have been poorly written

WYSIWYG - What You See Is What You Get
Some depend on context. SW might also stand for Storm Wardens if it is clear in that context that you are not referring to the Space Wolves.
CF might be Crimson Fists.
Occasionally you see LR standing for Leman Russ (the tank) among IG players. IG for Imperial Guard, btw.

"BFK" is another one used for Battlefleet Koronus.
Because of its relations to BFG, which is used for Battlefleet Gothic.
