I believe these type of interface messages are covered here: mw:Manual:System message

There is a problem with this thread. When I am logged out only the first 3 messages in this thread show up. Starting with your first post none of the following messages in this thread show up. So none of your messages show up. All messages show up when I am logged in. Bizarre. Per Bert, I think it's sufficient that there's a link in the wiki navigation. Also, it's not possible to add anything to the top of Special:Forum other than the button which is there by default. (The text of the button was changed with a system message, though).

About messages not showing up while you're logged out: this is most likely a caching issue, as all pages/threads/etc. are cached much more heavily for anons as opposed to logged in users, to reduce server load.

However, per this post by DaNASCAT, he thinks that new posts should bust the cache and so you should be able to see them while logged out. You may want to consider filing a bug report to Special:Contact/bug so that staff can look into it.
