The best idea for money is to have a different currency. Instead of dollars (America, Australian etc) or pounds (British) create your own currency. The best I find is $IM (sim dollars) or points, but it depends on how real you want the game to be

Will the players keep track of their own money, or will you run a bank? Some good ideas I have come across include:

• A monthly/weekly cheque send to the bank which is recorded down. If you want to do this you will need a bank page (with a table of money) set up and a form to fill out including name, password (optional), amount to be taken out of the account.

• A message board with each new string a players name. This is mostly reliant on the players and all you have to do is to monitor it and keep up with any unusual post. This can be a problem if some of your players don't post.

• Each transaction is sent to you. In this you receive a lot of extra email with each transaction to be done. This involves a lot of time on your behalf and you  have to keep up with the posts.

• Players monitor their own expenses. This can work well if you have honest players. This requires little to no effort on your behalf.
