I want to display an entry (in my case the first entry, where I give the visitors a welcome and an encouragement to leave a comment) in different language. Therefore again I want to use the Joomla! core functionallity for setting language strings and overwriting them in the language-overwrite section. Since now the Guestbook work like a charm. The point is intend to only one Guestbook for all tree language, so displaying "Guestbook Entry" and "Title" in multiple language would make the EBR even more useful for me.
