When I'm texting or on IM, sometimes I don't know how to signify the end of a conversation. I thought, maybe if I end my message with "oao" (over and out), it might get the point across. What do you think? Also, when I'm informing someone of something, I don't always like to say "fyi" (for your information), sometimes I use "jtlyk" (just to let you know). If you like these, maybe you can start using them with your friends and family!
