What do you call it when you think you’ve finished an IM conversation, closed the IM window but then the personĀ you’re chatting with gives you a little extra “seeya” or “l8r” which pops the window back open?
Please add your fav term to the comments.

Lol, I have an agreement with several friends, instead of goodbye we say CLOSE after which nothing can be said anymore.
PS: you should mark which fields are obligatory (ie the Mail field)
I like that! It makes me think of the “2 Generals Problem”[1].
Yeah my comment system sucks. Its on the list to revamp.
