I have a question about this
Runtime Mode
For small forums, most likely on shared hosting environments, with discussions, users, tags and pages summed up being less than 10.000 items. The sitemap is generated on the fly at each request.
What does it mean by "10.000 items"? Is that 10 links/pages on my site? When I added my sitemap to Google it found 66 links....should I change my setting to "Multi file" in operation mode on the sitemap extension?
