The "Gather" button, located underneath your menu instantly brings all participants to your location, which is a great way to guide new VR users through a model without having to teach them how to move, etc. “Gather[ing]” also allows you to have everyone simultaneously focus on the same part of the model.

You can also go to another user's location by opening the "Meeting" menu, finding their name in the participants’ list, and pressing the "Go To" button next to it.
