This is just an example on the use of the IncludeUpcoming macro. I'm using it seriously only in restricted wikis.

This is the monthcalendar:

<< <  2012 / 5 >  >>
Mon Tue Wed Thu Fri Sat Sun
  1 2 3 4 5 6
7 8 9 10 11 12 13
14 15 16 17 18 19 20
21 22 23 24 25 26 27
28 29 30 31      

And here I place the upcoming events, although they need not to be on the same page as the monthcalendar used:

Upcoming seminars

Upcoming seminars (with summary)

The headings into tables work in more recent versions of MoinMoin (e.g. tested in 1.5.6)
