Hey that's AWESOME. I've been trying to figure out how to use basecamp with more luck for GTD and this may be the missing piece. I've added one more thing to the 'contexts as people' approach and given each person my gmail address with a 'context flag' using the + email hack. (see https://mail.google.com/support/bin/answer.py?answer=12096&topic=1564) So I've added a filter to each different 'context account' email ie. myemailaddress+errands@gmail.com goes into an @errands label in gmail, just in case I want to use the 'Notify by email?' option in basecamp to remind me. Further to that, I could use another gmail filter to forward all of my @phone todos to my sms account on my phone... Endless possibilities if you ask me.
