Set up Flattr section in our Donations page

Some time ago we’ve decided that we want to accept donations through micropayment systems.

We’ve researched their policies and decided we would go with Flattr.

In order to allow people to donate, we need to implement that kind of link whereever we want to do that:

http://developers.flattr.net/auto-submit/ (that would be the no JS version)
