Following on from yesterdays post I spotted this on the DIY Planner blog. It speaks of a little piece of software which ticked some boxes for me. It allows me to create recurring tasks (a feature I'm fond of in Remember the Milk) but it has all the information offline. I've downloaded it for a trial, but seems to offer a lot of configurability and could fit nicely with my system.
