Maybe I am being paranoid, but I just want to be sure. I have modified two plugins that others have made (wp-quotes and countdown). I was hoping to get the plugin's authors approval/permission not only on modifying their plugins but also to see if they wanted to put my changes in their plugin. I am also concerned about the quotations content and have contacted some of the other quotes plugin authors about using their content in my modified plugin. I have only gotten one response from the deepthoughts plugin author.
With the creative common license, do I need to be concerned or just make a post here about the modified versions of the plugins and where to get them?
new to writing plugins.
