It's metagaming to say you were RDM'd in side? Even if you don't give a location?
Wouldn't it then also be metagaming to read that someone is robbing a store, has taken over a gang hideout, is stealing a kidney or is robbing a player of which, everyone in the server is notified?
I must say, I don't fully understand what metagaming is. Obviously things like switching to cop after seeing a drug deal go down is metagaming, as is saying (and acting upon) things like someone saying there is a player at X field with a hemmit in side.
But I've seen a post ( http://olympus-entertainment.com/forum/index.php?/topic/1357-the-definition-of-meta-gaming/ ) in which he describes the "definition" of metagaming (I understand he's not defining it literally, just using more colourful terms to describe what he consideres meta) to be server-hopping a robbery point - I don't understand how that is metagaming at all. Clearly it's using an exploit, but using information your character shouldn't already have? It doesn't.
