That's because you have to join them!
If you click Explore in the main menu, you can browse through thousands of Packs from 29 primary categories.
If you find a Pack that you’d like to join, simply click the “Join” or "Request to Join" button. Join at least three Packs to start developing your Perlu profile and growing your network.
If you're unable to find Packs that suit your interests, you can also create your own Pack and add or invite anyone you’d like.
The more relevant Packs you join, the more Collab opportunities you'll uncover!
