not yet, but I let my DH read some of the replies and stuff that I get every once in a while so now, when he's on his message board (for our local hockey team) he comes to me asking if I know what his abbreviations mean
Also, I have 2 girlfriends that are members of JM and every once in a while (usually when we're having a few drinks) we use some of the "JM talk" like BDing or baby dust and the people around us think we're nuts!!!
I LOVE IT!!!
