How does the page limitation work?
The Community and Small Business Editions come with limits on the number of sitemap pages that can be published. Once this limit is reached, you may create a page only as a draft and will be able to publish it after another page is taken down or “unpublished”. This does not include pages which are created dynamically (from blogs, forums, etc.).This limitation applies to all published pages, including page groups and home pages and does not restrict the total number of pages that can be created and saved in the system.
