Add license for website content

[tfar]

Please add a LICENSE.md file to the repo and also mention the license in the footer of the website.

A good candidate for this would be https://creativecommons.org/licenses/by/3.0/ .

I'd rather go for https://creativecommons.org/licenses/by-sa/4.0/ but that's only my opinion.

That's for future contributions, what about old content that has to be re-licensed?

ralphm to ping stpeter, as our IPR policy may say we use MIT license.

The IPR policy states "This document defines the official policy of the XMPP Standards Foundation regarding intellectual property rights (IPR) pertaining to XMPP Extension Protocol specifications (XEPs)." That policy was not intended to cover website content, but instead to govern contributions to the XSF standardization process. So IMHO it's up to us how we would like to license the other content on the site. Likely this will require discussion among the membership or a decision by the Board. As to existing content, we have had many contributors over the years and it would be difficult to contact them all or gain their approval for licensing. We'll need to make the best decision we can.

I think we can directly license content sub-sites and blog posts. And this from now into the future. Would it be sufficient to just place the license statement below the text / sub-site?
