It's driving me crazy. What is LOL?

At first I just assumed that it meant "Lot's of Luck," but in the context of many threads, it just doesn't make sense.

Also....when people refer to their spouse as their DH, what does that stand for? ("Designated Hitter" always comes to mind). I know the SO is "significant other," but I haven't a clue what DH stands for.

Is there anywhere on this site that explains all of the little abbreviations and acronyms?

Also, is there somewhere that will tell me how to put a picture on my thread?

Finally, what in the heck do the chicken legs represent under people's names?

I've been wondering these things for a couple weeks, but didn't want to sound like an idiot.

However, my confidence is soaring and I feel great about myself these days....so I really don't care about sounding like an idiot...

Thanks for filling me in!!
