I would like to have Paypal IPN integrated into my website. To explain what I need, first my site is a member based site using a content management system called LDU which can be found at [url removed, login to view] I wish to integrate Paypal IPN into this CMS, when a member pays through Paypal, I wish to upgrade their account status for 1 month period. A certain amount is needed before his/her account is upgraded. When the month period is over and the process is not repeated, I wish to have the account downgraded. I will provide further detail for whoever takes the job. Thanks for your time.
