I've done a decent number of largish GMed events, so I'll chime in with the "use a post order" thing. I tend to let everything happen free-form if there's no conflict happening: If it's a party, or a meeting, or anything like that, I'll just let it all go free-form unless someone is obviously being left out because they can't type fast enough.
With conflict - combat, for instance - I'll establish a post order, which naturally slows things down. I've started using /p and/or linkshells to help with this, though. I'll ask people, when it's their turn, to post OOCly in /p or the linkshell. Just a quick one-liner saying what they'll do. Then any rolls that are necessary are handled, and we move on to the next person. 60 seconds per person, tops. Then, while they're waiting for their next turn, they can craft up an IC post that has their action and its resolution (because we know if it's succeeded or not by that point) to be posted in /say or /em. This has been really helpful in keeping the action moving, so you might want to give it a try, as well.
