I haven't understood some of smf classifieds' features:
1) What are the "credits" and how are they used? I give free credits to me and to others but nothing changes. And except for "free credits" what other kind of credits exist and where will I find them?
2) What are the "listing orders"? What do they do? How can someone "order a listing"?
3) What is the "Custom Price"? Is it the price someone has to pay to put a listing? And what is the "Group Join Url"?
Can someone explain? Is there a documentation somewhere?
I really need to understand everything about how smf classifieds works, because I want to finish the greek translation.
