In YackPack you can create up to 45 packs with one email address.

Each pack can hold up to 100 people, although after about 50 people are in a pack, it can get challenging to see everyone.

YackPack automatically places your invitees in a pattern when you set up a pack. You can then rearrange people in the circle however you want. Just click on an avatar and drag it to where you would like it to be placed in the circle. Remember you can always roll over an avatar too and it will pop up bigger so you can see the image and read the name more easily.

The more people that are in your pack the smaller the avatars will all appear and scale.

Here’s what a pack with 60+ people might look like.
