Ace!
I was about to download activecollab yesterday when I discovered that you can no longer get it for free - I don't have time to go through the pain of persuading my clients to pay for stuff so I started looking for something else.. today I found just what I wanted..

ActiveCollab - free fork, with added basecampyness ! I'll be trying it out for the next couple of days - hopefully it'll be fairly simple to integrate with my client's existing wiki and mantis bugtracker.
