I am prototyping a collaborative knowledge base site at my current day job in Human Resources. This will document not only internal policies and procedures, step-by-step instructions on using the various software applications available, etc., but perhaps more importantly the rare (and not-so-rare) exceptions that too frequently get forgotten the next time they arise.
One important feature will be to not just document scheduled (daily/weekly/biweekly/monthly/annual) tasks, but provide reminders on schedule, allow them to be marked done with comments attached, etc. I initially looked at the event and eventrepeat modules, but eventrepeat (which creates a node for every repeated instance) is just too heavy handed. Moshe Weitzman pointed out that date.module has a Date Repeat API, so I'll be checking that out.
From the 2/20/08 Boston meetup, the NAT module may be worth checking out.
