Could someone please tell me how the bank works

You put your rupees in the bank. The bank will give you interest, and your rupees can't be stolen by other members.

So click Bank, click deposit points, enter how many of your rupees you want to put in it and then click "Deposit" Don't forget to click the link that tells you to update and return to main bank page. And you'll have deposited your rupees.
Be patient it might not show up right away.

To Withdraw click "Withdraw points" enter how many you want to take out of the bank, then click Withdraw and again don't forget to click the link that tells you to update and return to the main bank page and you'll have withdrawn your rupees.
Again patience, as it might not show up right away.

We aren't liable for any rupees lost in the transistion from the bank to your pocket and from your pocket to the bank. (Just like real banks!)
