             <p>Supporter-Only plug-ins are free for anyone who is an <strong>MB3 Supporter</strong> (with a valid MB3 key who has donated the minimum amount to the overall project).</p>
             <p>Anyone can install them and enjoy a free trial period of 14 days in most instances.  The trial period may commence as soon as you install the plug-in.<p>
                 <p>These plug-ins will appear in the catalog with a "Supporter" banner.</p>

             <p>Premium plug-ins are developed by third-parties and require that you be an <strong>MB3 Supporter <em>and</em> also register the plug-in with its creator.</strong>
                 The cost of registering these plug-ins is set for each one by its creator and all revenues go to that person.</p>
