Here is the list I think Eric was referring to, I can't find the actual thread but this should help to start with . There are lots of terms that are confusing but the good news about this forum is that there are more people willing to help you on this forum than there are terms to understand, so generally you will get an answer to any question you ask.
Oh yeah.....There are no stupid questions so ask if you don't know, the worst that will happen is a no reply and that doesn't hurt much!
