I have finally moved the Quake Expo 2011 site to the main CMS. The reason is that the expo has been originally built on a bespoke CMS, which in 2018 has lots of flaws and vulnerabilities. The content is better organized, better indexed and easier to find.
If you want to see how the original site used to look like, head over to Quaddicted’s archive or to the Wayback Machine.
