So just to clarify, we write a post, and announce an action at the end, with our roll, then you let us know if that's a success or a failure?

The alternate way is to announce your intention OOC and ask for a roll/counter roll. Once the rolling is done, proceed with IC posting based on the success of that action. This way you don't have to double post while also allowing everyone else to know what your intent is as well as being able to take multiple actions that require rolls in one post if need be.
