I am developing a script to show user created content on a page. Now I want to use a PHP class that has been released by the author under the GPL license. What I would like to know is if I will be able to use this script in my project.
A couple of things about my script:
It will be hosted on my website
It will not be distributed
It will be only available to users as a paid membership website.
I will not be releasing the source code to anyone
Can someone give me more insight to this regard?
