Ok...
So snooping about the Site today i clicked into the "more statistics," section and i found a whole bunch of stuff i hadn't paid attention to before...
The one thing that caught my eye was the section entitled "number of boards." by which the num,ber 18 was placed.
Now on a mental check, we have 15/16 boards here when including the three adult boards and the subboards in ask the trainer and the filesharing section....
Does this mean there is another board unlocked when reaching a post count landmark???
