BTW, it will take a little time to FIO, seems like we are talking an alien language here sometimes. It is so fun. IMHO you will learn quickly. WElcome to the board.
Here's a few more
ROFL - rolling on floor laughing
imho - in my humble opinion
ttyl - talk to you later
wip - work in progress
obw - one block wonder
brb - be right back
I am sure more will jump in with some. Have fun.
