Mike Filsaime has today announced his flagship software ‘Butterfly Marketing’ is now Open Source. That’s right you can now download Mike Filsaime’s ‘Butterfly Marketing Membership Software’ for free. Not only that, but you get the rights to the source code so you can add your own custom code and sell the resulting software under your own label.

This post is a brief attempt to throw some light on this question for those who might not be aware of Butterfly Marketing and the man behind it, my former mentor Mike Filsaime.
