    Hi everyone!
    The questions are simple. If developer create a free WP plugin and wish to sell plugin addons - what kind of license he needs for a plugin?
    As I know LGPL allow to unite GPL with non-GPL products, BUT WP says:

    "Your plugin must be compatible with the GNU General Public License v2, or any later version. We strongly recommend using the same license as WordPress — “GPLv2 or later.”"

    Is it possible to license WP plugin under LGPL?
    Is LGPL the kind of “GPLv2 or later.”
    Is it right to use LGPL for such situation?
    As I also know GPL provides exceptions ( http://www.gnu.org/licenses/gpl-faq.en.html#LinkingOverControlledInterface ), but:

    "But if you want to use parts of other GPL-covered programs by other authors in your code, you cannot authorize the exception for them. You have to get the approval of the copyright holders of those programs."

    Is it right to use GPL+ext to sell addons for WP plugin?
    Must developer to "get the approval" from WordPress about such extenssion?

    Thanks before!

    Simple answer: it needs to be GPLv2 or compatible. WordPress is GPL so derivatives (plugins and themes) need to be GPL as well too.

    Edit: That goes for plugin add-ons as well. It's part of why GPL is referred to as a viral license.

    Is it possible to license WP plugin under LGPL?
    Is LGPL the kind of “GPLv2 or later.”

    'Fraid not on all 3 questions.
