I've gone so far as to open a checking account at a local bank with a signature card that's got a stamp with some of the verbiage found around here and the internet. The stamp includes "full discharge demanded... pursuant to 12usc411 and 12usc95a(2). (I don't have the stamp in front of me right now). I've turned off direct deposit and have stamped the back of a paycheck as well as a check from Fidelity (sold stocks) and deposited these into my new account. I've received a debit card and checks from the bank, this is a non-interest bearing account.

My questions are this:

I've got lawful money, and nothing but lawful money in this account based on my check endorsements, and have photographed these and am storing the check images.

Now the question is, how do I access my money and keep it designated as lawful money?
How do I properly withdraw and use it? Teller with a withdrawal slip that I've used my stamp on?
Can I use an ATM to withdraw and even deposit since this is on my signature card?
Can I use my debit card to make purchases at the grocery store or Costco when required to use a PIN?
Can I use the mobile deposit feature, or is it best to see a teller to deposit?

Another question on my mind, I need to borrow some fiat money to buy a car, a different bank regularly sends me "superchecks" (loan checks that I can write to myself). Should I endorse these on the front in the Memo with my stamp, and the back since I'm writing this to myself? Then I'd have lawful money to buy car under $10,000 for all the benefits that may come with, and how do I turn a car title from a private seller into a lawfully owned car?

Also, when paying rent, can I use my lawful money checking account and do I need to stamp the memo line on the front of my check? Since I'm renting from a private owner, will I need to explain this to her, and suggest she just deposit them like normal? I don't want to cause her any trouble, just the Fed ;-)

Thanks for the great advice on this forum! Cheers from Denver, and I can't thank you all enough for all I've learned so far.
