Added to our to-do list. Thanks for suggesting.

You have still duplivate issue for meta title

1. For pages. For examlpe: https://wpforo.com/participant/annushka/activity/ and https://wpforo.com/participant/annushka/activity/paged/2/ and https://wpforo.com/participant/annushka/activity/paged/3/ and https://wpforo.com/participant/annushka/activity/paged/4/ etc 

All pages have one exactly meta titles <title>annushka – Activity – wpForo Support Forum</title>

also others any forum topics which include two or more pages (/paged/2/).

This is issue for SEO (you can check attached report pdf).

Solution: add automatic for all pages (exlude main) in title "number page"

<title>annushka | Activity | wpForo Support Forum | page 2</title>

2. Also this is possible if user create exactly topic title which ready on forum before. 

Solution: Add for post to metatitle "post id number"
