Hi everyone, sorry for the copy paste error. First, the date in the mail body should also be October 31, 2019 Second, due to daylight savings time differences between the US and Europe, the meeting is one hour earlier than usual for those joining from Europe. Therefore: This is a reminder of our regularly scheduled call today October *31* at 8 am Pacific / 11 am Eastern / *4pm CET*.
