If a file is no more than 15-20 MB, I can upload it to my server for the time being. I have a lot of space and I doubt I will use it all today and 10 years forward. I could easily reserve 1gb of server space for you guys.
This, if you can somehow send the file to me, for example thru cc-league chat:
http://sydby.com/carcassonne/irc/You can also mail it to me if your mail server can handle larger file. PM me for E-mail address.
I will then mail / message you back the url to the file and also make a simple html page in that folder for easy browsing or link to the file via download section here. Should work I believe.
The server is adfree with no download restrictions.
