I think, they are talking about a tag saying "this player is RP, you can interact RP way with him/her".
That's exaclty what I'm talking about. While PvP can be a part of RP, RP is more than just PvP. An all squares are rectangles but not all rectangles are squares type of situation.
I just think it would be nice to have BOTH a PvP AND an RP tag. To differentiate people who just want to fight, people who just want to RP and people who want to incorporate PvP into their RP.
