I read about the sitemaps there -- http://www.andrewsegawa.com/2011/12/add-sitemap-for-smf-2-0-1-how-to-submit-smf-sitemap-to-google/ and I saw a link to this forum, so I became a member of it.
I like it. Such a big forum! I also like http://www.seo-forum-seo-luntan.com and some other websites. I am from China, by the way.
Nice to meet you!
