I agree, there is no reason to meet unless we find other implementations

fjh: Do not schedule a F2F until we hear more

<Gerald_e> Where is the technical Plenary this year?

tlr: Suggestion, plan a technical plenary in the fall, right now there should not be a meeting in June, meeting once a year is useful, have the next one at the next technical plenary at TPAC

... Should be in Europe,

fjh: Good plan, justify a meeting, interop and meeting

<fjh> proposed RESOLUTION: Not have a F2F in June.

tlr: Location will be announced very soon
