Only whole threads can be pinned, individual posts cannot.
Only BOs (Board Owners) can pin threads, and ofc, the global staff.
If you are a BO, that is you own a board:
1. open the thread you wish to pin
2. click moderate thread
3. from the three checkboxes (lock, pin, cyclic) check the Pin
4. click Save
