'character' = 'toon'. when and why?

[DarkPetal]

I remember when PST started doing the rounds and the arguments in chat over why it was even needed. This definitely started in EQ as I had been playing some time before it started being used.

What's more amusing is most MMO's seem to use /w or whispering to denote contacting other players via private chat now, yet PST is still sticking about, much like the good old Ding! when you level.
