Site will consist of 12 individual html Landing Pages, all with separate, domain names. These landing pages will have a COMMON secure password login, that will take them to the main website(that will be secure). The main website will also be on another domain name. All 13 domain names use godaddy.com for hosting. Using Linux servers. MySQL and PHP.
The password from the 12 landing pages to the main site will change monthly. This will need to be automatic and emailed to a specified address.
The Main site has a library. We need a back end page to upload the titles and documents into the library.
Recommendations are welcome.
