Definitely too big to email, Olivier.
Here are the options (unless anyone can think of any more):
Start a web site - XT Host is incredibly easy, free and doesn't require you to give out any personal info. You would just need to claim a site and upload your file, no actual page making would need be done.
I can start a "DC Contest" Yahoo group for you to upload to (after you've joined the group). This would give us a place for others as well, if they don't have their own sites.
Have your archiver program create a multi-part file so it can be emailed over the span of several emails.
The first and second seem the best. It would be no problem for me to set up the Yahoo group, but I'm only going to do it if needed.
