Hi Broken,
I see that you are a new member.
I am unsure as to whether or not this is because, as a new member, you need to have your first 5 posts approved by Admin before they go "live".
This is just to make sure you are human
So yes, there would be a delay between when you made your first 5 posts and when they were visible on the board.
I hope this helps.
Take care.
