Joint Accounts good for credit?

[Workmanp]

I have a revolving account with BEST BUY that I opened with my brother as a cosigner YEARS ago.  Never late, always paid on time, and its still open.  I just havent used it in probably 7 years.  But, if I used it, for just some little 10 dollars purchases, and paid it off immediately, would it look good on both of our credit, or just mine as the primary?

Hi Workmanp, you might want to call the creditor and see if the card is still open. Being that long (7 yrs) they might have closed it due to inactivity for that long of period.
