There are two simple One-Bot-One-Bank scripts, for small communities. The first script, BankScript.txt, allows citizens, tourists and bots to have accounts. The second script, CitBankScript.txt, is only for citizens and is more secure, because citizen numbers are used and checked. Both scripts will log all transactions to file if you use x1 2.9999971 or higher. Instructions are provided in the zip as an html page.
