I think that it would be great to prefessionals if they could personalize their prezi’s links. (like for example to share a CV)
Not only for CVs, but to provide memorable URLs to coworkers also.
waiting for that, you may type the text you want in your text editor, set the page properties to the size of the text - set the link (even for mail) and save it as pdf. this pdf will be clickable in prezi, of course that’s working for an image either
