Okay, we need to start dividing into cells. That is, we need to split our core in half, one working in the docklands and the other in the store. That way, if the docklands fail we have no connection with the store half. Don't use the warehouse as "storage" for beds or whatever, don't have any connection at all, but do siphon beds off occasionally and send them there.
So I recommend the following:
Small Food Shop (Anne, Benny)
Two-Story Medium Shop (Clara, Dean, Eve)
Small Warehouse (Faulkner, Gideon, Heather, Ingrid) [0 Proles]
Docklands Recruiter (Jack)
Jack should be our recruitment contact, who does not have any connection to the others. He does not visit the warehouse or the stores, or anything. All he does is search for and evaluate recruits. The testing involves conversations, theft, trampling upon the flag, etc. If Jack thinks this person is a good recruit, he sets up a "meeting with the whole organization" in a deserted alley. This creates an opportunity for Jack to be ambushed by the secret police. If nothing happens, Jack tells the recruit where to meet one of the Warehouse people so he can be escorted to the warehouse.
We also need to set up signals. For example, if there is an X of tape on a certain window, it means the whole operations is compromised. If there is a string tied around a certain light-pole, it means the secret police are around. Etc.
We need a small van.
Begin siphoning off food and water, too, pretending to have sold it. One unit of each for every set we buy from the suppliers. Deliver it to the warehouse at night with the occasional furniture, in the van, but drive circuituously through the docklands to make sure we're not followed.
Begin scavenging hand weapons, even if they're just pipes and kitchen knives, and store them in the Small Warehouse.
Create a hidden cubby or something in each of the buildings, where any contraband can be stored. Only the Loyalists will know where the cubbies are, any Prole recruits won't.
Longer-Term Planning
It would be awesome to contact the black market and get laboratory materials. Then we could make our own moonshine, which is useful for sale and for molotov cocktails (and morale!). It would also make explosives possible, and whatever drugs we find out about. We could also set up water filtration. Farming would probably be too suspicious.
We need some kind of printing / copying machine.
