crediting contributors to presentations

My presentation is created and growing with help of others. I can only perfect it with input from other viewers.
Since Prezi encourages the open source sharing of knowledge, it would be great to have an opportunity to list the contributors to a presentation. Thus I could give them credits for assiting me and improve the rpesentation.
(Better yet: viewers could have a chalk board or a sandbox to leave suggestions behind!)

Hi there,

Great ideas. Until then, you can always list them in text at the end of your prezi and make it your last step.
