How connecting works (mutual and unlimited), how direct messages work, what the notification bell covers, and the report & block tools built into every surface.
Search people by name or @handle from the Connections page, or invite by email. The other person accepts or declines; once accepted, either side can message the other. There are no seat limits on any plan — your network is unlimited. Project invitations also land here: when a production adds you to its crew, you accept or decline it from the same page.
The bell in the top bar covers likes, comments, mentions, connection requests, applications to your roles, task assignments, project invitations and new messages — each notification routes to the right place when clicked.
Every post, comment and profile carries a report option (the ⋯ menu, or the Report link under a comment). Blocking someone hides your content from each other in both directions, severs the connection and stops direct messages. Both work even on public pages while signed out — you are asked to sign in first.
