To edit location details, go to the admin > Maps > Locations.
Click on the name of the location you'd like to edit. On the next page you can edit the details.
Capacity field specifies how many people can participate at a meeting / how many people fit into a meeting location. Meetings field shows how many separate meetings can take place at a location simultaneously.
To prevent meetings from being scheduled in a certain location, use the value 0 in Meetings field. If you want multiple meetings to occur in the same location at the same time, make this value whatever you desire greater than 1.
If unlimited amount of people should be allowd to use a location simultaneously, leave the Capacity field blank.
Remember to click Save at the bottom to save your changes.
To test this out you can log in to the front end of the website and create a meeting in that location.
If you wanted to further test this setup you can login as the administrator and switch to a different user and create a meeting at the same time in that location.
Depending on the limit set under the locations you may receive an error message which prevents you from creating another because the meeting capacity has been set to 1 for example.
Locations are also used to map sessions/booths/etc. These are typically set to a meeting capacity of 0 to hide session and/or non-meeting locations like posters.
Locations sort numerically, then alphabetically.
