<div>Ok, so lets start from begining.</div>
<div> </div>
<div>There is a open source gpl. I take the software and do some modifications.</div>
<div>I want distribute the code, everthing, but I wanna charge. Wich my options:</div>
<div> </div>
<div>1. Change the license</div>
<div>R: I cant ok ?</div>
<div> </div>
<div>2. I keep the gpl license but add a annex with new deffinitions. In this deffinitions I add how I am charging and some restrictions.</div>
<div>For example:</div>
<div>The four lays of open source is respected, of course. But I add if the software or some part is used</div>
<div>for commercial proposits I charge some $X for month or $XXX forever.</div>
<div>I can do that ?</div>
<div>R:</div>
<div> </div>
<div>3. If I have a open software gpl that charge $Y for commercial use. Can I do a fork of this project that charge nothing ?</div>
<div><br>Thank you very much,</div>
<div>Marcel<br> </div>
