I like to keep track of what my team members are working on. Unfortunately they don't use RTM yet - however I can still use RTM to stay on top of things.

I have a list called Team where I put all the tasks in. Each task gets tagged with t_xxx where xxx is my team members first name.

Example: t_john, t_suzy, etc.

Once a week I can go through the list, or when I am speaking to one of my team members about progress/resourcing I can jump to that tag straight away...

Simple, but effective...
