We have created a new section at the start of the MyMoodle page called "Site-level activity", to display blog activity and modules that are held at site, rather than course level. Relevant screenshots can be seen in forum posting http://moodle.org/mod/forum/discuss.php?d=77057.

The display would be similar to the following:

Learning Journal Entries
2 entries since last log in.

Forum: Arts and History forum
5 posts since last log in.
5 total unread.
Etc...

Within this section, first the blog overview function, which we have created within the blog code, is called to display information about activity in the blogs, if there has been any (see below for more detail). After that, the print_overview functions are called on all the modules that are held in the site course, (i.e. the introductory course of the site, usually course ID 1, if one has been set up), and the messages from these displayed.

The display of site-level activity may not be useful to all Moodle environments, (e.g. in some, there may be no interactive modules at this level, or the activity may be kept private) so we will put in a config. setting under My preferences/Appearance/My Moodle, which will allow the hiding or revealing of the whole section (the Site Level Activity box).
