Another great thing to have would be a list of all the labs (by country) that process super 8 and maybe even what their prices are and what they each can do. For instance FilmCraft Lab here in Detroit will only process Tri-x super 8 and will only do so on Wednesdays.
It would also be great to have a list of people and places that do transfers to various video formats/standards. Have it show what formats they can transfer to, if they do color correction, if they do sound transfers, what they might charge, what their address is, etc.
Suggestion number 4. This one is more lofty but just a suggestion anyway.
Sometimes I come to sites like these looking to see if I can find people that have films shot on super 8 on the internet that I can watch. Granted there are plenty of short film sites out there like ifilm. But those types of sites don't let you search out movies by the format or film stock they were shot in. Maybe you could host some short super 8 films here for others (like myself) to watch, critique and overall just to see what can be done with the format and the different cameras and film stock. Or at least have a link section that links directly to a bunch of super 8 films online.
