Assuming that you can only be part of one group at a time (one "LS"), I would not suggest creating an organization-specific guild but rather having a section on here to communicate, plan events and stories server-wide. For example someone could create a rogue type group that has already been present in the world and people can join it if they like it and it fits the characters. Then it's just up to the players to figure out what they want to do with it. Also there could be more than one knighthood (for example), with slight variations and different types of characters. Heck the leaders or command structure of these 'big' organizations could be made up NPCs, as long as they are kept constant, and used for RP. Just a train of thought...
I’m the bullies you hate, that you became.
