How It Works

Anyone can create a stak and any stak created has a unique code, and this code is embedded in the URL. For instance, a stak could have the following URL The last piece 9cPOrV4VKx, is the stak code.

Anyone who you share the URL (with the embedded code) with, will be able to see the stak and the user profiles. Those who do not have the URL will not be able to see the stak. There is no public listing of staks created. To add your card for a specific stak (or to create an stak) you will need to Login.
