So, pretty much anything that happens in real life is captured in the virtual environment, too. So, we are talking about engagement, areas of the space visited, downloads, viewers. You can measure how many people watch the video, how many people clicked on the pdf, how many people clicked on your website inside of the virtual environment. So, pretty much all depends on the tags that we create to track the information that you have inside of the virtual environment. So, it's pretty much anything possible to collect from an avatar and a speaker and booth and sponsor perspective. So, it's up to you. It's always connected with that idea of the embedded technology. So, if you have a Web site inside of the virtual environment embedded or if you have a PDF that is downloadable, we can put tags and we can track how many people downloaded it inside of the environment. Thank you.
