We have a secondary news website in Wordpress. I'm starting to tackle getting this one up to snuff, and one to-do item is getting a Marketo form into the sidebar widget (newsletter registration). I see there are a couple plugins out there, but they appear to be third-party solutions. I want to avoid iframing if I can. Though it might be fine, It brings up a security alert that I'm trying to avoid, due to the nature of our business. Looks like there may be a way with Smart tags - but I'm a little rusty in Wordpress.
