SEO for vBulletin 5
 

How is the SEO for vBulletin 5? I have the forum installed on a subfolder on my main domain so the forum can directly effect the SEO for my entire site. In the past I ran into an problem with the activity stream, in the members section, creating massive amounts of duplicate content pages and blank pages and with Google Panda it really hurt my SEO for my site, which I am still trying to recover from. So I guess what I am looking for is, has anyone noticed any dips in traffic, increase in number of pages indexed, or any other signs that this version could hurt my site's SEO, since using vBulletin 5?
