Hello, the script looks great, but it bothers me that a registered user cannot write any comments on the searched file and it also bothers me that he cannot rate the file with his thumb down or up, or with stars.
I just responded to your ticket for the same. There's no comments or "like" functionality in the script at the moment. You can suggest it in the RFCs section of the forum and if enough people do the same, it'll be considered for development work.
You could also source a PHP developer from somewhere like upwork to write the code. Any developer with PHP knowledge should be able to work on the code.
