I've made a start uploading some of my files:
So far I've uploaded some photos (high res and low res, with a few animated gifs), and all the mp3 files I have from that promo-CD. There are some good sound effects in there, which could be useful to someone I'm sure. They are just the sound effects as mp3s, not those fuzzy clips that people have captured over the years, the ones that still have the music in the background.
I'm debating whether or not to upload the video files I have, there are quite a few, and also they came from ProjectViper. I guess as long as I give credit it shouldn't be a problem, and if he ever rebuilds the site I can remove them (or host them for him).
