So let me start be explaining what I like about the rule.

- It makes it extremely easy and convenient for other roleplayers, especially newer ones, to understand the situation.

- It stops any confusion as to where the person is and who they are speaking to.

- It helps players who are new to the roleplay easily insert themselves into any situation.

Let me now express a few issues with it.

- Some might find it aggravating or simply redundant to apply to their posts

- Some players might not use the Posting Rule and end up causing complications in the IC that need to be sorted out in the OOC

- Finally, a player that misuses it could cause mass destruction and horrific scenes in the roleplay

That being said, most of the issues with it are error of Human Beings and thus the rule could only be a little improved based off the negatives. I completely agree that it would make the roleplay easier to use that rule. 

with the that being said, being said, it also means that players need to be more observant of OOC, IC, and CS's in order to thrive in this roleplay.

Just hope to point out that I made this post with no harsh attitude nor offensiveness on my mind. Have a nice day :)
