if possible, just a iframe button (like a hyperlink button) would be nice. It is hard to remember every time and write down iframe code is not very handy…
Codepad is actually very useful(and powerful) when answering simple stuff and much more easier for newcomers to understand what is going on. Seems like there is a wasted potential there.
<iframe width="100%" height="800" frameborder="0" scrolling="no" marginheight="0"
marginwidth="0" src="CODEPAD_URL"></iframe>
