I often have trouble expressing my self correctly in my native language, so doesn't except German to be any better.

I operated one bot, PDFbot (Diskussion • Beiträge • hochgeladene Dateien • SBL-Log • Sperr-Logbuch • globale Beiträge • SUL • Logbuch), that was updated the file size of PDF links before being deemed unneeded.
