Autoresponder service -script modification and installation

Modify existing PHP script to allow subscribers to signup for a free autoresponder service. The script is this: <[login to view URL]> I need you to modify it in a way that it will disable or limit the import feature. Let me explain better: if a customer has an existing list and wants to use my services may want to import his list. Since I am offering this for free then the "import" feature will only be allowed for paying customers. All you need to do is to install the script on my web server and modify it as per my instructions. Please let me know if interested...
