I should be able to temporarily upload the outtakes, at least. I'll have to see how big the rest of the files are and which ones were already available elsewhere.
Edit: All right. As Shiku said on the first page, there are five subfolders in the Extras folder: Artstuff, Desktops, MTS Models, Music, and Sounds. The music tracks are just the high-bitrate FS2 battle track MP3s that have been around for a while, and the desktops are the three that have been available from Descent-Network, so those are taken care of. Shiku already posted all 9 of the art pictures. The sound folder comes out to around 700KB when zipped; I've uploaded it
here.
The MTS Models folder is another story; it's around 70MB unzipped, and I was able to get it to around a 34MB RAR. However, I don't have enough webspace to host it. Unless Shiku can manage to upload it, the only way I'll be able to get it to anyone is by uploading it to an FTP, sending it by IM, or by splitting it up a few ships at a time.
