I have noticed an ongoing 'bug' in the dnforum software.
When clicking on View New Posts sometimes many old posts also appear, ones I have already read. For example, a few minutes ago dozens appeared that I already read.
However, at other times it seems the opposite is so as not all new posts are there, only a few of them. When I go back and look at the threads I see new posts there which were not on the View New Posts list.
