I work in the Real Estate Business and the purpose of my project is to develop a Web based Application which roughly does the following; 1. Allows Users can create PDF and HTML Documents on the fly. For example, create a PDF brochures describing a property. 2. Authorisation and Authentication based on Type of User. 3. Website Administrator must be able to ensure that contact between Users of the Application remains anonymous (ie they cannot contact each other without my knowledge/approval). Users must however be able to contact each other by E-Mail. Users will be programmatically assigned pop3 accounts when they register. It is important that I have records of all the E-mails users have sent. 4. Users have to pay when creating PDF documents (using Paypal PIN).
