Hi Jesta,
I just launched a project on chainbb (you might want to take a look as it may catch on) and as I was crafting it I wrote text and added a Youtube link at the end of the text on the same line. When I previewed it the text vanished but the video thumbnail was there. When I toggled back to the post the text had not been deleted. To correct it I went to the end of the text and hit return to create a new line after the text and it worked.
Have a happy 4th of July if I don't chat with you till then. The site is really shaping up. Good job!
