What does one have to do to unhide a post?
Akismet is one system we use to filter spam. It just requires someone to review your post to confirm it is not actually spam, and then your post will appear.
Why was your post marked by akismet as possible spam? In my memory, akismet is usually triggered by identical-duplicate posts, and posting too frequently, i.e. multiple replies within seconds of one another.
Not totally sure in your case, - I honestly don't recall seeing it, sorry.
