RSS Reader FAQ

Can I use your rsslib.php that is under MPL 1.1 when i am a "company"?

See the license:

Is it ok to use your rsslib.php, that i have customized, as background for my gadget in facebook and other Web2.0 Social Platforms?

Same response. I would appreciate that you link on a page of your site to the original script page.
