The most direct option, as I alluded to yesterday, is to just get a (often free) consultation with a lawyer and talk to them. Get a few answers, ask a few questions, and see if the questions you have lead you to a place where you need to consider retaining a lawyer on a more long-term basis.
The key here is that you should listen to your common sense. The options I have presented lead you increasingly toward actual talk with people you can verify are lawyers and therefore should have some expertise. These options also lead you increasingly in the direction of actually needing/having/paying for a lawyer. If you need to go far enough to post on Avvo, follow up, and/or have a consultation, maybe you actually need a lawyer to help you. If you're just goofing around and finding things on the web, have a good time, but double- and triple-check before you take what you hear as gospel.
