It's for people who can't read long strings of text because they're too attention span starved and lazy. It means "Too Long; Didn't Read"

I understand how you feel and I've seen on LS chat about dumping parties that suck and reforming in town. I've done it a couple of times myself. It happens, dump the party, reform then or later. But why come crying here like it's going to solve anything? Most of the time, people don't care how you feel in game and they most certainly couldn't care less about your feelings on these forums. If someone hasn't learned to mind their Ps and Qs from their mom why would they learn it from you?

Just my 2 cents. Go have fun out there.
