Implications of creating a plugin that adds functionality to other developer’s plugin?
I’m thinking in writing a plugin that alow users to import quizes on an existing LMS plugin, that functionality isn’t even exists on the paid version of the existing plugin.
Is there any legal impediments of publishing that plugin on the wordpress.org repositories?.
As this question states, any plugin published on wordpress.org is under GPL license (the LMS plugin falls in this category), but the paid version is not under those terms.
I don’t plan to charge for the plugin, maybe open a donation channel, but mostly I just want to make it as a portfolio item to show to possible employers.
