Licensing

[Steven Sherry]

Hey, I used the FancyBoxThumbs extension in Mediawiki on a website for a company and I'm wondering if I have to buy a license for it. On the extension page in Mediawiki it says the extension is free if it's for a non-for-profit website. The website is not designed for profiting, but more so as a glossary defining mining terminology and mining practices along with the mathematics and physics associated with it. Here's a link: http://www.iring.ca/wikiTest/index.php?title=IRing%27s_Blasting_Wiki#

Do I need to buy a license or not? 

Thanks
