Hi Nick,

That's not a general email addr.
It's the addr for the Nouveau75 'support group' on Groups.io
It's a subgroup of this main 4SQRP Group

I don't think you can email to it until you join... go to
https://4sqrp.groups.io/g/N75
to join up

There will be more info available in the files area of that Group

Jim, N5IB
