Some communities allow you to invite your friends to join.
If enabled for your community, you can invite people from outside the community to
join. When you invite them, they'll receive an email with instructions on how they
can set up their account in the community.
Click People (This may be located under the Browse menu).
In the left pane, click Send Invites. You won't see this option if your administrator has disabled
the ability to invite people from outside to join your community.
To add an email address to your list of recipients, type a complete email address and click the
link that Jive creates.
Edit the note if you want to tailor it for your friends, and then click Send
