Dear Creditnet: I run several small businesses and am looking for the best travel rewards business credit card. I plan to spend a few thousand per month on each card and the balances are expected to always be paid in full. What do you suggest?

 Dear Creditnet: I have finally received my first credit card for bad credit after bankruptcy. My question is do I charge $400 to the card and make minimum payments over time to establish a track record, or do I charge $40 to $50 monthly and pay off the entire balance?

Dear Creditnet: My wife and I have excellent credit scores, but we used to only have one no annual fee credit card with a limit of $10,000 (balance is paid off each month). I recently opened another credit card with better rewards and it has a $20,000 credit limit.

I've been told not to close out our first credit card account, but should I lower the credit limit on it to somewhere around $500 since we won't be using it? Or will our credit scores be negatively affected by lowering our available credit limit from $30,000 to $20,500?

  Dear Creditnet: I have nine years of credit-history and while my credit is "good", it's not "excellent". I'm currently interested in applying for a top-notch rewards credit card, but my chances of getting approved seem to be much higher if I apply for the student version of the card. So my question is will a student credit card have the same effect as a regular credit card on my credit score? And what about rebuilding my credit-history? Will a student credit card help improve my credit just as much as any other credit card?
