Chris-777,

AzzidReign,
you should submit the following to google:
http://yourforumsroot/sitemap_index.xml.gz
http://yourforumsroot/sitemap_1.xml.gz
http://yourforumsroot/sitemap_2.xml.gz
etc.
(although files are stored in vbseo_sitemap/data/ folder, you should address them in the forums root using the mod_rewrite rules added in .htaccces file)
edit: replied nearly simultaniously, yes this is definitely a frequently asked question
