I see in the ongoing discussion in the chair selection process that there has been some questions regarding the role and commitments of the chair:

The "Job Description" can be found in RIPE 542: "Working Group Chair Job Description and Procedures"

https://www.ripe.net/publications/docs/ripe-542

As others have stated, it is not necessarily for the chair to be present at every single RIPE meeting. It is however always good to meet in person, at the WG meeting, the WG chairs lunch and informally with other chairs, RIPE NCC staff and myself.

While I have enjoyed virtual life for close to 30 years - I do still see the value of meeting in person now and then.

Hans Petter Holen, 
RIPE Chair
