Thank you guys. :-D I think I'd go with just leaving a link. After a couple of days from the posting of the article, when I find there's no more edits that may be needed, I'd contact Sean.

I got some embed code from a youtube video and vimeo video. so that's an iframe. And I think codeproject html output encodes the article.. so the iframes are not rendered but rather just printed as on the article. yeah I could understand the security implications of embedding iframes and third party content, but considering all our articles are moderated and reviewed by community leaders... my best guess is this is allowed, I am just hitting the wrong corners. <a href="http://www.codeproject.com/Questions/685402/how-to-embed-vimeo-video">how to embed vimeo video?</a>[<a href="http://www.codeproject.com/Questions/685402/how-to-embed-vimeo-video" target="_blank" title="New Window">^</a>] <a href="http://www.codeproject.com/Questions/362338/YouTube-video-insertion-in-my-article-doesnt-work">http://www.codeproject.com/Questions/362338/YouTube-video-insertion-in-my-article-doesnt-work</a>[<a href="http://www.codeproject.com/Questions/362338/YouTube-video-insertion-in-my-article-doesnt-work" target="_blank" title="New Window">^</a>] Browsed around the Q&A and FAQ section, couldn't find anythinng helpful. I am writing an article rather than explaining some portions in text, I thought I could link one of my videos from youtube or vimeo. Is this allowed in codeproject? If embedding content via iframe is not supported, is there any other way I could imbed/insert a youtube video on my article? Below is how my embed code looks: <iframe allowfullscreen="" frameborder="0" height="315" src="https://www.youtube.com/embed/somevideo" width="420"></iframe> <iframe allowfullscreen="" frameborder="0" height="281" mozallowfullscreen="" src="https://player.vimeo.com/video/somevideo" webkitallowfullscreen="" width="500"></iframe></x-turndown>
