Hello Mike,
i read the license and usage. But i will be gone safty!!!
I understand this:You do not have to keep the Gantry or RocketTheme links and logos in the frontend, however you must ensure that all copyright notices in the code are retained. Also if you intend to use the Gantry Framework in a commercial project, or a template you intend to redistribute in any form, please retain a "Powered by Gantry" logo and link in the backend administrative interface.
Ok, you mean with "commercial projects" -> "Sell Templates" too?
