Can I run more than one venue from one account?

Yes, on a venue account. Each venue you add gets its own profile, calendar and team, and you switch between them.

Adding a venue: open Settings and go to Team & site management. On the Add a venue row, press the plus icon at its right-hand end. That opens Your Venues; press + Add a venue, fill in the Venue name, City and Venue type, and press Add venue. This creates the new venue's profile - fill in the rest of its details from its profile afterwards. You can also start from the venue icon at the top of the Dashboard; it has no words on screen, and hovering it says Add a venue, or Manage venues once you run more than one.

Switching between venues: once you run two or more: on a computer, open the account menu from your profile picture at the top right and pick the venue under Acting venue - a tick marks the current one. On a phone, tapping your picture opens your account page instead, so switch from Your Venues. Your profile and availability then show that venue. Your Venues lists them too, and choosing one there switches as well.

Sharing the work: in the same Team & site management section you can invite people and choose under Which venues they help manage. In Settings, the add and invite rows appear only for the person who leads the team. See can my band members help run our profile?
