This is intended functionality; the idea of a topic being pinned is to make sure that people will see it - once they’ve done so, there’s little reason for them to read it again - and thus, little reason for the topic to remain pinned for that particular person.

- Click on your account name.
- Switch to the Preferences tab.
- Open the Interface section.
- Toggle whether Automatically unpin topics when I reach the bottom is ticked.

will result in this image being embedded;
Clicking the upload button should show the permitted file extensions;
I would expect there to be a fairly exhaustive guide to the forum package and how we have configured it at some point, however this would take a significant amount of time to work on, and it’s difficult to prioritize it over other work (e.g. Patch 0.7.2).
