From http://support.openoffice.org/index.html click Issue Tracker to get to http://qa.openoffice.org/issue_handling/pre_submission.html . From here, enter a search term to look for existing issues (e.g. "mail list archive link") and click "Search". This leads to a page saying:
  Not Found
  The page you were looking for doesn't exist.
  You may have mistyped the address or the page may have moved.

Also, from http://qa.openoffice.org/issue_handling/pre_submission.html clicking "Go on - submit the issue" and attempting to search from there leads to the same message.

Apologies if this is a duplicate - I have been unable to check for existing issues!
