If you are the creator of a pack you have the ability to invite and add people to your pack at any time after the pack has been set up. To invite more users to one of your packs follow these steps.

Login to YackPack at www.yackpack.net. Navigate to the pack to which you’d like to invite new members. Click on the circular button with an envelope icon that says “invite.” It’s near the top of the left-hand side of the circle (at about 10:00). Enter the name and email addresses of the people you would like to invite and click to go to step 2. Enter a subject and some email text that they will receive as part of their invitation. Click to send the email invitations and then click to enter the pack.

You will see the newly invited people as part of your pack. You can arrange them in the circle wherever you would like. If the people you invited are new to YackPack they will appear with gray smiley face icons. If they are already registered in YackPack you will either see white smiley face icons or images they’ve uploaded for themselves.

If you are not the creator of the pack and click the “invite” button, it will tell you who the pack creator is. You can then send that person a message asking them to extend an invitation to the person you would like added to the pack.
