Alright, so I've made it so people can disable smileys on an individual basis. I've added a YouTube embed code. Unfortunately, I can't implement the HTML code but we do now have a paragraph formatting button with which you can use CSS to format.
That's quite alright- I understand you can't implement it! It was only a suggestion, and I'm quite alright with the option you picked instead. Thanks for checking into it!
