Lorea tasks plugin and email notifications

The tasks plugin from the Lorea project is a real gem and seems to work great with Elgg 1.8.18:


(Why don't they opload their plugins to this community page by the way)

But documentation of it seems to be non existant :(

As far as I can tell, users should get notifications about changes in task status (and maybe before a deadline?), but on our side that doesn't seem to work.

Especially regarding deadline notifications I assume you need a daily cron-job somehow?

Would be great if someone could help me out with that. Thx!
