Hi NS,
I just launched https://trickipedia.xyz/ , an encyclopedia of skiing tricks. Currently you'll notice that there are only two tricks on the site, and that's because I want to use video examples provided by the skiing community. Other websites with the same idea for other sports, like http://www.club540.com/tricktionary for tricking, just use videos taken from pros. But I thought that getting the community involved would be more fun.
If you feel like you have a trick down perfectly and want to be featured as the textbook example of the trick, go on to the submit page of my site and send a video! Rules for submissions are on the site, and all skiers featured will be given full credit (filmers too of course). Eventually I want the site to have everything from front 270s out to triple 18s.
Thank you!
