robots.txt for vbulletin 4

What is a good robots file to use for vbulletin 4?

Is this one adequate:

http://www.vbseo.com/robots.txt

Thanks

In my opinion the robots file you should make it to yourself, That's about what you want search engines to index or not, However in vbulletin 4 I didn't see anything that's should be edited since vb3 to vb4 on it so use your old one or use the vbseo.com robots and don't forget to add the sitemap line :
That's if you installed your forum in your site root

Code:

Sitemap: http://www.yoursite.com/sitemap_index.xml.gz

And this code if you use vBulletin in any sub-directory :

Code:

Sitemap: http://www.yoursite.com/vb-root/sitemap_index.xml.gz
