This page has a list of archives of the User talk:Herzbube page.
The first post of a discussion is relevant for filing the discussion in a particular archive. This is important because I am often absent for weeks and months (or even years!), so there will be long gaps between questions and replies. For instance, a question may have been asked in 2011, but I have answered it in 2012. Although the discussion has found its resolution in 2012, it will be filed in the 2011 archive.
