If you've never done forums they can be quite odd! For instance, here - some topics are very on target and deal with tiny details, but most also have areas where people chill a bit more. The only advice is to read as many posts in the areas you are interested in as you can and get a feel for the people who post there.
Some people join for help, others join to GIVE help - because they are know it all curmudgeons like me. We are also multi-country, multi-cultural and often multi-languaged. For every answer you might get, others will have a different one. Look at it like joining a sort of like minded club - beginners and exceptionally skilled people all with a common aim - recording and music. Occasionally people go off on crusades, and get really upset. Don't worry. Best advice is think before you post - it's really awkward when the answer to your question might already be in the topic, on a previous page - that really annoys folk. If you ask a question, take the time to at least do some of the work. Also make sure you give useful info. A common one is somebody saying I've recorded my guitar and there is a strange noise, what is it? The first answer says "can you stick a sample up we can listen to?"
Have fun - pretty much there will always be good advice - but sometimes it comes after a few days when the one person who knows, logs in.
