The project consists of the creation of a membership database to be as secure as possible. The core functionality of the website will be to allow users to create listings (ads) of some sort, details of which I do not wish to dislose. Each member will have a trading history attached to their ID's, exactly like eBay's functions. With each listing other members have the ability to respond in a similar fashion to a forum response. I guess the core functions of a forum with ebay form of script.
