The features you mention are being worked on - a couple of people have volunteered to help with the programming.

I just wanted to point out that in the weekly view one week is always one week (the display is like a calendar, really)... the topic view, however can be completely flexible.

I'd say you've added a line of code somewhere in the print_course_categories() function in course/lib.php

Whoops ... loose end. For future reference, you should never upgrade only part of a Moodle installation. For a given release (eg 1.0.9), there may be new 1.0.9 modules which you could add to an installation, but the rest has to be upgraded all at the same time.

Ah! That makes sense!

Yikes, indeed! That's a first.

Usually if the mail send fails then they get marked "sent" anyway, so it shouldn't be repeating like that. You need to work out if it's Moodle or your mailer.

Are the mails all coming to the exact same mail address? (just in case you have lots of test accounts you might have forgotten about).

Is everyone getting the same number of copies?

Are the timestamps on each copy of the same message the same, or different?

If you run admin/cron.php manually do you see any error messages?
