I am on v10.3 and I wondered if it was possible to:
a) mark all threads in a forum as read
b) mark all threads in all forums as read?
I found this in the v11 documentation but couldn't see anything for v10.
Marking all threads read in all forums isn't directly exposed, but could be accomplished by iterating over all forums and calling the $core_v2_forum.MarkAllAsRead() API on each.
Found the answer to a) - the forum links widget has a mark all read button for forum pages. Just b) now
So, this isn't something a user could do for themselves then. OK cool, thanks Ben!
