A lot (maybe even most) of the people who visit are "guests" looking for specific information, and a lot never post or read threads. A very obvious feature should be instructions (in words of one syllable or less) on what the DT is and how to use it. "Digital Tradition" isn't really an instinctively-obvious name for "searchable list of songs and lyrics".

Also, the rules on how to name threads should be somewhere on top.
