After having posted being unable to develop phpEselGui in the future (free time...) some "fans" of this project already decided to develop phpEselGui.
Have at look at member list of the project, we already had some nice discussions on what to build in the next versions. Discussions can starting now be read on the new mailing-list "phpeselgui-developer".
Maybe you also want to choin our team? Feel free to ask one of our admins how you can help us to build the best GUI for mlDonkey...
