Packs are where Collaborations happen. Share Collaborations with your fellow Pack members that meet the qualifications of the work that needs to be done (See How to Setup a Collaboration).
The more packs you participate in, the more Collaboration opportunities you will have to extend and receive. 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? Invite them. Then add them to a Pack and let the Collaborations begin.
