Gameplay videos.

Create a Youtube account if you don't already have one and upload the videos to it. Once they're up and processed you can simply paste a link here or even embed them in your post by using the youtube tags.

You might want to compress your recorded vids first though, as generally Fraps recordings are quite large. I just use Windows Moviemaker. You can try uploading them uncompressed, I'm not sure if there's a filesize limit for the vids you upload to Youtube. Obviously it will take longer that way, depending on your connection.
