# Invite collaborators

### 1. Create a whitelist of permitted wallet addresses

While creating an empty collection using this guide:

{% content-ref url="curating-a-collection" %}
[curating-a-collection](https://blindboxesnft.gitbook.io/blind-boxes-marketplace/curating-a-drop/curating-a-collection)
{% endcontent-ref %}

the curator has the option to make a whitelist of collaborators. This is optional. Only users that are on this "guestlist" can add NFTs to any given collection. 

### 2. Send collaborators the collection link

Send the URL link of the collection to the users on your whitelist to invite them to join your collection. You can find this link in the address bar of your web browser when you are in the collection library landing page.
