For those unaware, you can use the 'Insert Flash Video' button just above the smileys in post creation to generate the video code in to your post. Then place the video link in between the code like Example: [flash code]http://www.videolink.com/1su32d47?[flash code]
Customizing the =425,344 in the code will allow you to increase or decrease the size, we suggest no more than =525,400
Also adding the 'center' code to the start and end, will align your video for better viewing.
Example: [example][flash code]http://www.videolink.com/1su32d47?[flash code][/example] replacing the word example with the word 'center'.
