Domain Trader is a PHP script which was developed to allow webmasters & domain professionals to manage their entire domain portfolio. It features a powerful domain parking module which operates similar to other popular domain parking websites such as Sedo, DomainSponsor etc. Domain Trader has a built in auction system, which allows potential buyers to make offers on domains that are for sale. Users are able to categorize their domains for sale and also supply "Minimum offer" and "Asking price" values for each domain. It also has a Page Rank and Link Popularity checker.
