From about 1993-2010 FILMUS-L was a major internet film music discussion site. No pretty pictures but some great (and heated) discussions on film music featuring most of the same arguments as have appeared in FSM over the years. Many of the current FSM posters also appeared on FILMUS-L as well. It's a good source for arcane film music answers and sometime vitriolic debates.
Interesting. I always find it fun especially in light of the recent expansions/reissues trend to see what people thought of the original albums and this board's search engine doesn't always comply. I'm sure there are some insightful threads to be found on this older board.
Edit: so far I've found some funny threads discussing the emergence of CDR's and MP3 and lots of vinyl vs CD threads.
