There’s an Unread Posts tab on the Forum Menu bar or there’s a little black icon on the top right of the Forum column. The Latest Topics that have been created are listed on the right of the Forum column.
You will also find a double ‘speech bubble’ icon to the left of each forum section. If it’s blue then there are unread posts in that section. If it’s dark grey/black then there are no unread posts in that section.
If you have a lot of Unread Posts that maybe you don’t want to plough through, go to the very bottom of the Forum page and under Forum Statistics you’ll find a link – Mark All Read. That will remove all Unread Posts from your list
