How can a mere mortal give back to the empegbbs user knowledgebase?

Often, I think of questions that I know you all will have answers to. But what do you call a community member who always takes and doesn't give back?

Sometimes, I'll see a question that I hope to answer (ie: about Microsoft Office), but it already has multiple good replies. Curses, foiled again.

Does anyone else feel this way? Haha, help us to help you. Thanks everyone!
