Dear Creditnet: I get credit card offers in the mail all the time that say they have no pre-set spending limits. Does this mean that if I'm approved for one of these cards I can charge as much as I want? I run a small business out of my home and have had trouble getting a credit card with a high enough limit to cover my monthly expenses, so a card with no pre-set spending limit sounds like it could be the perfect fit. - Rebecca from NC

Dear Creditnet: What's the advantage of paying off credit card debt that's still within the statute of limitations but already charged off and sold to a collection agency? If it's not going to help improve my credit scores right away, I'm beginning to think I might be better off just keeping the cash in my own pocket. -Adam from VA

Dear Creditnet: I wanted my son to have a credit card in his name when he went off to college. However, the only way we could get him a card was to apply for one in my name and add him as an authorized user. He used the credit card responsibly for the last four years and upon graduation was able to open a new credit card in his own name. We'd like to close the old one now, even though it doesn't have an annual fee, but we're concerned about how this might affect both of our credit scores. Should we just close it since we don't plan on using the card again?

Dear Creditnet: I already have pretty good credit scores in the 790's, but it kind of bothers me that I can't seem to break the 800 mark. I've tried for years and I just seem to be stuck where I am. Is it really worth the extra effort to try and raise my credit scores above 800? - Megan from TN
