'New' Post count on migrated boards

[#1]

On the  Plusnet Community / forum 

 page,  the 'Posts'  and 'New'  columns are both showing the same numeric value for all the boards copied from the old site.  This is making it difficult to track the various threads I was following now that the migration is complete.  Having to visit every board to mark as Read will be very time consuming.  Any chance of some Global change to make 'New' only show the count of New from today and onward?

You don't need to do this on each board, if you go to Unread Topics (there's a button lower down the page) you can then mark all as read.

Easy answer is to mark all threads as read and then only ones with new posts will show here https://community.plus.net/t5/forums/unreadpostspage/tab/thread

Thanks Chris,  but if I take that route it will mark all of Today's post (so far) as read.

It will indeed, unfortunate side effect of the migration
