Awesome web based application development tracker and cheap to boot.
For those of you looking for a way to track feature requests, bugs, tasks, and time lines to a lesser extent, and you don't want to spend an arm and a leg look no further than Gemini from Countersoft. It's only about $95 dollars US, depending on what the dollars is worth compared to the pound at the time of purchase, and if you limit it to 15 users or less and don't put it on a public webserver it's free!
It's helping me become alot more organized. I can't recommend it enough.
