[At-Large] Nect Conf Call Sep 10?

According to the ALAC wiki, next monthly conference call is set for Sep 10, which is Monday. I thought we agreed to have monthly call on every second Tuesday. I read the meeting summary, but there is not mention about the change. Could someone clarify? (sorry if I missed some other information or email). AND, what happened to the ALAC Board liaison vote? thanks, izumi
