Do I need to make a large purchase and let it report somehow? Its my first charge card...ill do some searchin. Just rrally hoping for the backdating!!
What you need to do with this card is charge responsibly and PIF every month. It does not affect your overall util. on any FICO other than TU98 (what you get here). That score is more educational than anything.
I would run bills through it you normally pay. Don't get too loose with it, it is very easy to rack up a bill on it.
