Jesus, I didn't see that.
Ok, you're means you are. Their is for saying something belongs to someone.
there is a word used to indicate something, there was a kid who tried to post thirteen seconds of bike clips on a scooter forum and he is an idiot.
your is also a possessive word, meaning a word that shows who owns something. meaning your clips should have been posted either in the clips thread or in the other sports section.
Learn to use the language you have been given before you try to post next time please.
And for the mods, I can't imagine riding a bike because of how heavy they are, let alone trying to 540 on one. Good job.
Next time think though.
