There are only three rules:
1. You can post here only if you have more than 100 posts for this site (not just SSS). This is to keep out the "looky at my band!!" people who post a video or whatever and never come back.
2. You are allowed only one post within a seven-day period. This is to make sure that everyone gets equal exposure, and also, to inspire people to show only their best work.
3. You can add as many attachments as you like to that post (currently 5 maximum with vBulletin), but be aware there are size limitations. You may need to, for example, re-render a video for lower bandwidth, or link to a post you made on YouTube or your own site.
I picture this thread as something people can look through from time to time and see/listen to Cool Stuff. Have fun!
