As you probably know, OpenFX has joined the ASWF. These old Google Groups lists will be shut down and their contents migrated into the new list,
openfx-d...@lists.aswf.io, one week from today, Oct 18, 2022. That list is archived and searchable at
https://lists.aswf.io/g/openfx-discussion. Please sign up there if you haven't already.
