Gaping

I am also wondering if anyone knows (or thinks they know) how these MMORPGs manage the animations for spells and such. Do they save the movement and the spell as an animation, or do they have two separate animations - one for movement and one for the spell? I'd imagine the answer's the latter, because the target's location changes.

Also, do you guys know if you have to press <enter> to start chatting, and then <enter> again to finish?
