About two months ago, I started using Alex King’s Tasks software to keep a to-do list of projects for the consulting / sysadmin / webmaster work I do “on the side”.
Over the weekend, I ugpraded to the “commercial” (non-free) version, Tasks 2.0.
This is one of the simplest, yet the best, pieces of software I’ve ever paid for. If you’ve got a PHP/MySQL-enabled web server or hosting provider, try it out. Just from being able to properly keep track of things on my to-do list, I’ve got increased productivity – and in return, very happy clients.
I highly recommend it. If you’ve got a multi-user environment, look at Tasks Pro. I may eventually upgrade to it so that I can give clients a login and have them add projects directly.
