What should happen is let anybody submit tips, but dont let everybody submit tricks. That way you dont have the "1440 Meat Grabber" bullshit. Have a list that looks like:
Spins:
-180
-360
-etc
Grabs
-mute
-etc
And then you can click on one and submit a tip. If something is missing, a person could go through the site admin to get a new trick in there.
