Thomas:I have been using Jetsi a lot and only had a problem one time — my correspondent had very poor WiFi — other than that, it has worked very well, including a 90 min interview with a professor from Tokyo University on fuel cell buses.-- Chris Peeples --P.s. Do any of you understand why Ubuntu 14:4 LTS has a problem w/Zoom 5 (AC Transit uses Zoom, have not been able to get them to use open source).
