This paper argues that currently there is a lack of powerful and easy to use, coordination support systems designed for non-professional users. To address this problem this paper proposes a novel approach to the coordination of projects. The approach is based on integrating minimalist task workspaces in web-based Task/Participant tables. The paper presents a further design of Tabula, a web-based coordination system that implements this approach. The concept and prototype of Tabula was explored in two user studies employing the focus group method. The groups included subjects that were active, respectively, Master students in HCI and high-school teachers. The results of the focus group will be presented and discussed. The improved version of Tabula implements novel interface- and coordination functionality as well as an alternative e-mail based interface.
