There's no set post order, outside of when we get into obvious things like combat. So yeah, you're free to post. You're free to have your character set off and try to do a quest, stare blankly at their phone, try to talk to X, whatever you want. As long as speedposting doesn't get too bad, all is well.

As an aside, everyone's who's posted so far has been sent a PM with their dice roll and current quest log, in case there's anyone who didn't notice.
