I would love the ability to post a comment and embed iframe content such as polls or videos.

Here is an example of the code:
<iframe src="http://www.bedloo.com/bedloos/what-should-i-do-next-with-my-jeep-cherokee/embed?aspect=blogsize" frameborder="0" width="560" height="315"></iframe>

Thanks!

 

Good luck. I don't see that happening.

 

Almost no forums allow this due to cross-site scripting vulnerabilities. It'd be a wonderful way to steal information from every forum user.

Also most browsers have disabled iframes with sources in third-party websites for at least the last 5 years

 

Plus you can add a polls and videos already with relative ease.
