Hola traveler Tanja, welcomed back to CA & thank you for the follow up. 
Jakartees, 
From my side, I recommend that this call & any Jakarta calls that are public in nature get move to the Jakarta Community calendar & not be housed under the Jakarta PMC calendar.
2 reasons:
- general: PMC and anything related to it means Project Management, as such it might deter many whom might know little or nothing about how easy it needs to be to become a valuable Jakartee with hands on getting stuff done without heavy hand-holding.  
 
- bias: I don't like needed links to be shared via email as a set requirement to collaboration in anything relevant to open source projects that have distributed data on multiple sections such a drives, calendars, etc.  As such, I recommend the Jakarta EE twitter handle is used to create a link and send maybe like 2 reminders to its community, such a link can be sent to the Jakarta EE Community email forum as stand-alone reminder without further commentary.   Simplicity rules and it cuts disperse data, I call - "content debt" to those of us,  who are aware of the project itself. Further, at a later time, it makes content inventory and its tracing a nightmare.   Jakarta needs/must and ought to be look for how-to- standards that make it easy to stay, enter, stay informed & own processes by being a part of the process itself & providing direct feedback via public mediums, such as this thread follow up. :)
