Just a thought: New topics still show up on top, so I can imagine someone creating the same topic every day, while archiving the last one.
Are you sure about that? I don't think I've seen a new topic on the front page of the ANN board yet since the bumping change.
Tested and it appeared near the bottom of the first page..
Maybe my bump power worked on the OP? Not sure how minibump power works on new OPs..
Moved it to archival..
