Block Search engines?

I have read all the merrits of what VBSEO does but was wondering if there was an option to actualy block search engines from spidering certain forums but still allow them to take full advantage of VBSEO for the others?

You can use a robots.txt file to disallow spiders from spidering certain forums.

You would add the rewritten names to the robots.txt file.

Example:

/forums/general-discussion/
