The "cooperative" nature of my system is that anyone can provide labor directly for my system to gain initial credit, which credit can then be used to post RFBs to hire others. (Some of the services my system provides to users will be dependent on such labor-for-the-system to build up various databases needed by those services.) There will be no limit to how much credit a person can acquire via performing work for the system or by working for others, hence no limit to the number of RFBs and working contracts simultaneously in effect. (There will, however, be a limit on the total amount of un-used credit any one person can accumulate, and a limit on the total value of any single contract. My system will support many small quick tasks rather than any individual long-term contracts, thus force diversity of investment in RFBs.) TOP
