On Download page ([http://piwik.org/download-piwik/]), down below there's a broken link to Previous releases.
The actual HTML is:
<a href="#">Previous releases.</a>
The fixed one should be something like:
<a href="http://builds.piwik.org/">Previous releases.</a>
Keep up with the great job!! Keywords: link documentation
Thank you for your report. I've just fixed that issue.
