Is gravity forms GPL? The reason I ask is if its GPL that gives the the right to modify and distribute it. I don't have 200 to spend on a developer licnese for for now my plan is to buy a single license, modify the code to bypass the license key check, and set it up for my clients. I am willing to directly support my users myself, and its worth saving 160 to me. When it comes time to upgrade I would re-assess the possiblity of getting a dev license but right now thats not an option.
thanks.
