It was about time. I finally managed to upgrade guaka.org to Drupal 7. It was actually very easy once I had my Aegir setup fixed. I just needed to migrate the site to the Drupal 7 platform. Like often with technology, Aegir can be quite nice when things work smoothly.
Next I have to clean up the site a little bit and customize the Bootstrap theme that I chose as a base theme.
In the past week I also started fixing some issues on this website on which you can buy stuff on Ebay and Amazon with your bitcoins. Then, to stay with the money topic, I set up Moneyless.org, which is started as a translation of geldloos.nl but has the potential to become much bigger (as it's in a bigger language).
