Is it possible to replace external resources - which are currently integrated with the forum - against internal solutions?
It's fantastic that you've replaced GoogleAnalytics with Piwik and that the project is hosted within the EU

and it would be also great if you could get rid of googleapsis.com
I wouldn't expect forum users to get nervous if the forum would be a bit slower then... It's super fast anyway.
