IF you've asked for details or potential results for your actions, either here in the OOC or via PM to me directly, you can finish a task before I make a GM update-for-all post. That said, if you want to finish a task before a GM post, keep in mind that your character will be disjoined from anyone else in the timeline until they reach a similar point as you.

Thus, I'd recommend not tryint to finish too many things on your own, unless you're by yourself, or have no intentions of interacting with other characters for a while.
