Hi,
In a forum when you click on view replies etc in tcat, when views descends there is written ascending when it ascends there is written descending!
I don't think it's a bug.. It doesn't state the current sorting direction, it notifies the user about their possible choice (thus it's a link).
But it states the current sorting direction. Just click on asc or desk below tcat titles, then you will see that the order of threads changes.
By default the last post column shows [asc] link while it's descending (newest first). The link has ascending order parameter (&order=asc at the end), so everything is correct.
EDIT: no counterargument for a while, so rejecting.
