I RPed quite a lot a few years ago. It's great fun for you and everyone else reading it if your RPs are done up properly.
The best way to roleplay IC events is to RP your decision as you make the decision, or shortly after.
For example...
If you're a ruler, and you want to RP your decision to go to war, do so just before you click the "declare war" button IC.
Or if you want to place a bounty and RP why you did it. Place the bounty first, then RP your thoughts.
That simple.
