Modeled literally after Crusaderpay (Thanks Illumina!), Presidents-Pay is basically just a credit card for IP. It should be self explanatory filling it out. I just have to mention a few stuff.
1. Your balance each month is $100. Record your purchases in one of the 2 banks in IP.
2. If you go below $0, y o u a r e i n d e b t.
3. If you have a job, then your balance will depend on how much money you have. Do the math.
