If anyone wants to create such a site for a conference series, I can post that person's emai address so that past attendees can send material (printed material saved by attendees can be scanned and posted). Good candidates for such sites would be EuroComb, AWOCA (Australasian Worshop on Combinatorial Algorithms), CTW (Graphs and Combinatorial Optimization), Ontario Combinatorics Workshops, the Cumberland Conference on Combinatorics and Computing, the MCCCC, the Southeastern International Conferences, Graph Theory Day in New York, etc. I'm sure there are also many other series that would benefit from having such sites.
