It is very easy to configure, either in backend or in frontend.
It is cleary structured, even the files. Once you found out how it is structured, it is easy to customize.
I've seen a lot of other auction components for Joomla 1.5, none of them can do what AF can do!
Even there is missing the function to edit the auctions themselves from backend or frontend in this version, it fulfilled my expectations.
Good support and great component!
