As far as I know, newbies can't post in the investigations sub-board too. Only members and above can post there. This is not supposed to be a problem for OP as this sub-board won't be visible for him in first place (I just felt he needs to know about it).
OP, post anywhere you want as long as the forum software allows you to do so and what you are going to write is on-topic and may add value to the discussion.
