Lately, All I have seen is forums creating mass spaces. Mostly on posts with youtube videos embedded.

My assumption is this could be a embedded issue with the youtube videos though it's strange if you push enter once to leave an empty line when you post it leaves massive spaces.

For example when I first posted that I had to play around with backspace all day till it looked decent.

another issue is when you copy from another page then paste you get highlights so if you copy or cut from another website or profile page that is white or another colour in the background when you paste into the forums. So for example Know of the games but no longer own consoles. So let us hope these classic companies keep bringing us the arcade games to steam! - See more at: http://www.cimmarian.com//social/forum/topic/42

I copied that from the forum topic I posted at the top now all my font will look like this.
