Here's a bit more info you may find helpful, lenticular1:
The WXForum is divided into multiple forums, each with a general description regarding what information should be posted on a specific forum. For example, this it the 'General Weather/Earth Sciences, Tropical Weather' forum and it's purpose is to house discussions pertaining to tropical weather.
Within a specific forum, you/others can post a Topic (the first message) with a description and content. As you/others post replies to that topic, it becomes a 'thread' of discussion pertaining to the subject in the Topic (first post in the thread).
Expected WXforum behavior is to post ONE Topic about a specific subject, and not repeat the post as a new topic in the same forum (or other forums) -- doing repeated content posts as new topics is (as Jachym noted) viewed as akin to spammer activity and may be subject to action by the admins/moderators.
Hope this helps,
Best regards,
