On the administration area of Auction Factory you can find the Users page, containing a list of basic user information and some management tools.
Registration can either be handled by Joomla or by the component, depending on the Profile Integration settings, users will need to fill in the Auction profile and to agree with the Terms and conditions of your website in order to use the auctioning system. Users will be redirected to the profile filling page when attempting to access Auction Factory menus until said profile is filled. For example, when attempting to post an auction.
Viewing auctions does not require a user profile or even logging in.
On the Users page you can check their emails, names, statistics about bids and auctions along with their Status. You can also Block/Unlock, allowing you to ban that user from the Joomla Login and automatically from Auction Factory related actions.
Users with Verified and Powerseller ranks can receive differential prices for the payment items. These prices are set in the config of each payment plugin.
Clicking on a username will take you to the details page of the respective user.
On the details page, you can see personal details and statistics related to the user (including custom fields) along with the user balance, messages, ratings and bids.
