When the option "Board Active" is set to "inactive" and the message about "maintenance" appears on forum home, users that login as registered have all notices appear, even when they closed them before.
It would be great if even in the "maintenance" state, the board would respect the closed notices. Otherwise it is irritating.
Other wise there would need to be a disclaimer "you can close this notice if you no longer want to see, however the board reserve the right to make you see it again when we close the forum for maintenance."
So this is a bug IMO due to inconsistent and misleading behaviour of the notices system.
But if there is a reason, ie under what circumstances it is useful to have users' dismissed notices reappear purely due to forum being closed, then that's fair enough - but what could that reason be I wonder?
