You can limit, filter or change the sorting of the blog stream in the settings of Lively Blogs.
The maximum number of displayed posts and the time frame on the dashboard can be configured with the parameters "Maximum number of regular posts" and "Time frame" in the dashboard section.
Blog posts on the dashboard can be filtered by labels, authors and and spaces under the section "Featured posts". If one of these filters is used, a new category "Featured Posts" will be added to the blogs overview page.
Blog posts on the dashboard and on the blogs overview page can be sorted by the creation date, the modification date (when a blog post was edited) or by the date of the last comment.
