Decision Making

Due to the limitations of the online format, I'd like to discourage people from taking actions that split the group. Even a short combat can take 20-40 minutes, and if 2 PCs are in combat while the rest of the group is 30 seconds
away, then half the play group doesn't get to do anything for a while. That is not fun.
I don't mean to discourage scouting, aerial surveillance, or even "opening that door while everyone else is over there." But do try to limit the actions that will likely put your character in danger while at a distance from the party.
Also, when the group is deciding where to go, I'd like a rough consensus. If a PC wants to go charging off alone into the wilderness, I'm just going to ignore the request unless at least half the group backs him up*. And if a player repeatedly uses the threat of going off into the wilderness to force the other players to agree with him, I'm calling that a bad play style and warning or banning the player. Alternately, if the player insists that his character would go off alone, the PC goes off charging into the wilderness and is eaten by a grue.
I don't really expect this to be a problem, I'm just trying to set expectations.
As far as rough consensus goes, it's strict majority vote. For issues that are split down the middle, the side that has the most PCs with positive Reaction modifiers wins. If the PCs with positive Reaction modifiers are split, the character with the least negative Reaction modifier has the deciding vote. Again, don't be jerks about this, please.
