I've been using ProjectPier on and off for a minute now, from the days when it was ActiveCollab, and I love it. My problem though is that this lovely project management doesn't have a user friendly GUI when it comes to adding text. So I went looking and found nothing.
As a result of my searching I came across a textile editor and decided to make a hack. Now you can add a textile editor to ProjectPier instillation with 5 simple steps. Enjoy!
