Real-time environmental management is a team game, which the new SiteHive feature of allowing you to see and manage who has access to your sites, makes a lot easier!
In Site Details you'll now see a new section: Users. In this section you can see who currently has access to your site, and invite any new users you want to grant access to. Clicking invite will allow you to enter any email address, which will then be sent an invite to join that site.
If the email address already has access to SiteHive they'll just get an email to ask them to confirm the new site should be added to their portfolio. If they're a new user, they'll get an email with a link that will allow them to add their details to create their account, then will have instant access to the site.
Coming in the new year is the ability to remove users from a site, resend invites at the click of a button, and portfolio level user management. Keep the ideas for new features coming!
