Thank you Jean-Daniel:

We really appreciate all you do for us and your commitment to keeping us
running. It is really fantastic.

Our team upgraded Gerrit versions yesterday, which went well, now it
seems today we have multiple issues to contend with, isn't that always
the way. :)

Give us some time to discuss what you suggest and get back to you with a
response as a team.

We really appreciate your desire to help us and are very grateful for
your responsiveness on all things.

Thank you so much,
Anita.
