That is a good idea, unfortunately it is prohibitively difficult to implement with this forum software. I don't think we can "voice" people per-thread, only per-board.
The RP forum moves roleplay from the game where it belongs and is in context with the CHARACTER to the forum where it is out of game and out of context with the character and even the player account, connected to the forum account which for many people is not immediately connected. The disconnect is considerable for readers unfamiliar with the player. I do think that people who enjoy roleplaying should do so in-game.
It's not an either/or situation. One can roleplay in the game and also post it to the roleplaying forum. I don't know of anyone who does the latter without doing the former... while many people do the former without doing the latter. The roleplaying forum is really just not a problem.
