All, we've setup a Skype conference dial-in to let you dial in to our sessions today. Andreas' Skype account name, which we use for it, is andsavva The first part (9-10:30am EDT) is about the Activity Instance Schema, the second part (11am-12:30pm EDT) deals with general JSDL issues. You are welcome to join us at any time. Regards, Alexander -- Alexander Papaspyrou alexander.papaspyrou@tu-dortmund.de
