quick report of WG status is something that Mario Merri requested when he was the Area Director. Marc Duhaze requested continuing it while was he was Acting AD, and Daniel Fischer also requested it be continued. Let me know whether or not you find it useful.
I usually provide it after each of our WG telecons.<o:p></o:p></span></p>
