How can I add multiple people to a space at once?

When creating a new space or after clicking the Invite People link in the Space Members section of a space, you will get an “Invite People” window.  You can select multiple contacts from your Kona or type in multiple email addresses separated by a semi-colon (;).

For example: userA@kona.com; userB@kona.com; userC@kona.com

After entering a personal message if desired, click “Send Invites” in the lower right corner.  Invitations will be sent to all the users you entered at once.
