We changed the Announce category almost a year ago (ref) to not allow replies. It is also noted in the about for the Announcement category
Note : Use of this category will not allow for replies to the announcement. The intent being that each person should start a separate topic as needed to avoid a cacophony of divergent replies.
The reason for the change was an announcement was made and turned into several off-topic discussions that were a distraction for the OP and others. As such the admins here decided to clean up the category and not allow replies. Now each reply is flagged for moderator intervention and not automatically posted.
If you notice the Announcement category has no replies.
If I am not busy I will let the OP of the reply know why the change was made with a personal message.
If you are releasing new or updated software and would like the topic to receive replies then use the category Releases which does allow replies.
