To post a video here on Trapperman, it has to be a Google, MySpace, Yahoo or YouTube video. Copy the link for the video at the top of the page the video is on. On Trapperman, select the button that looks like the clapperboard they use to cut scenes in movies. A little box will pop up. Paste the link into the box and click OK. You may have to type a letter there first before pasting. If you do, just delete the letter before clicking Ok. Then post your post like you normally would.
You can also just type [video:youtube] before and [/video] after your link.
