For me, I do it the old way, Write paper notes, Stock them all on a wall, order them in order of tasks needing to be done and do it that way. It means I am able to see everything that needs to be done and for me, its the best way to manage what needs to be done.

But, for large projects or for a mass of e-mails from users I have started to use Project to allow me to orgainse the work load.
