SEO - how to unlink the usernames??

[JustinBr]

Hi everyone - I am looking to unlink all usernames on my forum index, as well as the thread listing.

On the individidual threads themselves, I want to keep the usernames linked. How do I do this?

I am not sure what you want to unlink, but why not use the robots.txt file if you want to forbid spiders from parsing certain URLs ?
