On the main site, we have a gm and players tag. However, these seem like they are vague. For GMs we have gm-techniques and gm-tools, and everything else I can find that's tagged [gm] seems to boil down to one of those. Similarly with players we have problem-players but not really player-techniques...
With gm I'm really tempted to synonym it to gm-techniques after a quick scrub to find any outliers. With players I'm more torn, but both seem very unclear in and of themselves. Is gm asking about killer GMs from a player perspective, learning to GM from a GM perspective, what?
It doesn't help that just about anything in RPG.SE could be tagged player or GM (or, I guess, designer for the rule/setting creation questions). Seems like a meta tag to me. Thoughts?
