oh, ok that´s kind of misleading.
This is "the board for the unregistered and not logged in".
It only contains three postings, about what´s inside and some login troubleshooting.
This is read only for everyone, there are never more postings, no movement at all, so I figured out the display limit is kind of unimportant here,

All other forums are configured properly, I take it this forum can´t be responisble for the blank out.
