I'm not sure what's with the hostility, but I'm more than happy to provide additional information.

Of the major players that would include a sitemap you have Xenforo and vBulletin, the former being a subscription based system and the later being a much more expensive product.

IPB's sitemap option is a user contributed addon with little support provided by the developers.

Discorse offers a sitemap, but it's open source and assistance is not provided by their development support site.

I am a Web Development Contractor, I do not work for UBBCentral. I have provided free User to User Support since the beginning of these support forums.
