Your T-bank account.
Monthly and online statements.
Just like a bank account, you'll receive monthly paper statements showing "deposits" and "withdrawals." You can access and manage your account online fairly easily.
Adding and subtracting T-dollars.
Each time you give or receive services, either the provider or the recipient will need to record the transaction. I find it easiest to go online myself, select the person with whom I did the transaction, fill out the online form and then it's done. Sign on here and use the email address you provided CCE (the administrators) to get access to your account.
Checks and balances.
Lest you think some evil person can drain your account of your duly earned T-hours, they can't. Each time a transaction is posted online, the giver, the getter and time bank's admin all get emails announcing the transaction. Fraud would be spotted right away if I got an email stating that So-and-So just provided me T-B services, when, indeed, they hadn't.
Spontaneity is just fine.
While it's certainly a good strategy to post your services offered and wanted, exchanging services on the fly without any official posting on the web-based bulletin board is just fine, too. Just make sure that you track your credits and debits, as you are responsible for this component of the process.
Managing your own account.
Manage your account online. Post services you're offering. Search what other T-B members are offering, or post what you're looking for. Add or deduct time to your account. Click here to access your account online. Adding and deducting time right after a service exchange is a good habit to develop.
