Packs are where Collaborations happen. You can share Collaborations with your fellow Pack members who meet your qualifications (See How to Setup a Collaboration).
The more relevant Packs you join, the more Collaboration opportunities you'll discover. Build Packs of your own or request to join existing Packs.
Are there people you’d like to work with that aren’t on Perlu? Feel free to invite them! Then, add them to a Pack and let the Collaborations begin.
