In mEducator most of the content is organized under workpackages. 
For example, every Announcement, Event, File and Forum topic belongs to one workpackage. 
In the left panel of mEducator web site you can see (after you've logged in) a menu, under the title WORKPACKAGES. 
By clicking for example in 'WP1- Project Start Up' you'll see (under the clicked item) the types of content for the specific workpackage. At the same time, mEducator brings in front of you a new page, contains all types of content from WP1, ordered by posting datetime.
Click on Announcements (under the item 'WP1- Project Start Up' ) and you'll see all announcements from Workpackage 1.
