Share a thread into a second forum without duplicating the discussion.
How to use:
- Open the thread you want to crosspost.
- Click the Crosspost button in the thread header.
- Pick the destination forum from the dropdown.
- Confirm.
What happens: a new thread appears in the destination forum with a short note ("Crossposted from …") and a link back to the original. The new thread has an empty body — readers follow the link to read and reply. Replies happen in the original thread only.
When to use: an announcement that's relevant to multiple platform forums; a question where you're not sure which forum fits.
