I know that they are not created automatically. But I wondered whether they are used (indexed, listed,...) in some automatic way that depends on the title or one post per week.
IIRC the sidebar used to have a link to the latest open thread, which I think was based on the open_thread tag. That seems to have vanished now.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
