There's really only two RP servers -
Aeon and Agharta
The rest are just labeled as such wrongly :(
Kitsune keeps saying they are, but they aren't obviously a dedicated RP server. I had always thought that tag was for dedicated servers, not ones that have communities that just "support" RP (or anyone could claim that)
You have to been patience to the new one that signed up in 1-2 days, they'll get removed when they get checked.
Don't remember TagzRO having an RP sign originally they might have put it up some time for fun ...
Vintage have a story there in the front page. I think that might mean something.
The RP tag meaning can be flexible, if they server say they are RP and the player "support" RP it's better than those that claim they are RP but is nothing at all.
Now 4 left.
