There currently isn't an option to send invites from within group or junior packages to anyone who isn't the main contact. To find out how to invite the main contact from within a membership, click here.
Please Note - You can invite junior and group members individually from within the contact profile in the Contacts Module. Invites can be sent to anyone as long as they have an email address on their record.

Click on the 'Profile' button next to the member you would like to invite. You will then be taken to that members contact profile.
Once you are within their profile, click on the blue 'Profile Options' button in the top right-hand corner and select 'Invite Contact'
This will bring up the following overlay:
Click 'Submit' to send the invite, and you will then see a confirmation overlay:
