You can add a Gif, icon, text, or anything else as a link. In our Freelancer demo, we just dropped an icon in there (using the icon widget), but it’s intentionally open-ended so you can use anything you like.
Very rarely do we get contact form issues. There’s generally nothing we can do about it anyway since it’s server related.
The only potential difference with Fusion is that if you’ve enabled the AJAX feature and a contact form that doesn’t support AJAX (the included Contact Form 7 does support AJAX though) then you might run into issue. But you’ll notice these immediately since you probably won’t get any error or submission notification.
