1. Metagaming; good or bad?
I have done some LARP in the past, where metagaming in an of itself is often seen as value neutral. You can have good meta and bad meta. When harnessed for good, metagaming will cause more interesting player interaction, create cool scenes and stop rule breakers from ruining good gameplay. When used for bad, people will be excluded from fun stuff and people will strive for selfish goals.
I think under the current rules most people intuitively agree that some meta is of course okay. Especially if it is not a current event. Stuff like announcing the boxing events and posting gameplay videos long after the events within took place (streaming is somehow an exception though, hehe).
2. Good meta
Still, there are several things I would consider good metagaming that might still be considered against the rules. My examples:
1: Posting time and location of a public event that's going to happen or is happening.
2: Announcing that you have a shop open at X location where people can buy and sell stuff.
3: Agreeing to having a fight between two factions at a certain time and place.
4: Posting a riddle to the village location.
5: Publicly calling out someone and challenging them to a duel (obviously calling out their character, not the player. That could be harassment).
Basically, I think of good meta as things that would be announced in the local newspaper, on the radio or on a town square IRL. We have no newspaper and because we don't all play at the same time there's no functional radio or town square to announce things from.
3. Radios right now
Some of this could be fixed by the devs eventually. Currently the radios don't work well, since the signal is dropped in a stupid unrealistic way when you push and release the PTT button, and because they are fairly rare. I've tried and failed to talk to someone I heard on the radio, but the voice was just chopping out. I held the button down for very long and tried to tell him to do the same, but we could only hear fragments of each other, I think. If/when they fix this and add a noise filter for long distances like they did with the voice filter for gags I think we can change the meta rules to be more radio-based.
4. Forum vs. discord?
5. In character / out of character channels on discord
What if we had separate channels for in character /out of character messages? The in character channel could function sort of as a replacement for radios in the game and a bulletin board, but should still have some restrictions since it would be quite a bit more powerful than the in game radios ever will be. This would also create a clear separation between accusations and arguments between players and player characters (some confusion has arisen regarding this in the past, where crass language has been censored).
