75911 member/data management script

i have a number of quiz scripts which i want to give select access to people who signup to my advanced member section so i need a php/mysql solution for the following (i have examples of most of this in the attached zip file) - member signup - email verification - login page - password reminder page which will email password if user enters username or email address - paypal payment system (subscription and individual test credit purchase options) - ability to generate test links they can send to friends, and they will get emailed those test results (allow me to specify the variables and result email format for each test that will get emailed) each test taken subtracts a test credit from their account - ability to add additional tests to the tests page - for subscribers all results get recorded to mysql database - name, date test taken, name of test, all main type percentage scores (which varies from 8-10 depending on the test) the type description names are different for each test (but since there are only 4 types of tests, that is just 4 description name sets) - a page for subscribers which shows the results of each test taken in 2 drop down boxes, so they can compare different people and/or tests, - subscribers who cancel or don't renew their subscription get an email saying in thirty days their test database records may be erased, allow me some option in the code to specify when and if i want former subcriber's databases erased, in any case once their subscription ends they lose access to the database. - email screen so users can email generated links to friends if they want, the page should automatically load the link, the user's name and email into the from field, leaving only the reciever's email and an optional custom user message to be filled out - all files should be in folder /advanced, all the test scripts will be in a cgi-folder /advanced - if they are not a paid member or have no credits they should get a message instructing them that they need credits or be a member to get access to advanced tests and features i want two versions of the above as you will see from the attached folders (advanced and advanced plus). the second version has some additional features and while the above makes use of a number of quiz scripts, the new script will access one central standardized quiz script, just changing the question sets and results variables for each test (i will also run it from a seperate mysql database and folder).
