Seo mod

Yeah but that VB mod. is not free. As for SMF, you can enable it in the Admin Panel if you're running it on an Apache server.

PhpBB requires a mod., and SMF has a better one out right now. As for MyBB http://www.spicefuse.com offers one. They all require mod_rewrite though, so if you use Windows hosting they WILL NOT work!

So if you plan to use SEO mods. as a tip, stick with Linux hosting, unless you're going to have an ASP based site.
