Hello M.Braam, welcome to vBUsers!
I made the jump from phpBB to vB about 2 years ago, and I've never looked back.
This skin isn't downloadable, unfortunately, as it is the signature skin for this site.
Good luck with your vB!
Yep yep I've got the generator on both of my sites and it DOES work!!
Every single day, if even one new post has been made on my site, the SEO generator submits the new sitemap to both yahoo and google. I've seen a marked increase in both spiders and visitors to my sites, especially to Top vB.
