I have alot of wordpress themes I am going to be releasing soon, and I am wondering what licence I should include with it? GPU? Or something close. It needs to say in it.... "must keep copyright holder links on at all times" Obviously better wording, but you get the point of it! Thanks in advance.
A Creative Commons "By Attribution" license suits Wordpress templates well. You can also decide if you want to allow modifications (recommended since people will want to customize your theme to their site), and commercial use. http://creativecommons.org/license/
