>For the YouTube - and the thumbnail pictures. Yes, I would like to turn that off for the messages I read, like the abbreviations. For the messages I create - there are three ways as I see. Keep it as it is, allow the poster to set the usage or allow the poster to control position of the stuff. for example ba placing it into a tag. The somehow unrelated placing of the videow on bottom is strange at least.

We will add an option to turn off YouTube visual thumbnails.
