I've always been surprized at the number of smart people asking questions here that have been answered several times over.
The built-in search routines here are fine for finding a post by a specific person or one that you remember part of, but not for answering a question you have the first time.
The best tool I've found is using Google with site:astaro.org.
Perhaps a Google search button could be included here that automatically adds site:astaro.org to each query.
