On the topic of creating individual sigs for regions or shtetlach:
In doing so, we miss the benefit of shared learnings of the whole in a
region where Jews were always on the move. Create a Special Research
Group, sure, but how many people would benefit >from that group having its own discussion group versus the number that would benefit >from their
continued participation in the U SIG.
If you have a group of researchers interested, start a research group.
Create a Shtetlink, translate documents, contribute to databases, but
stay under the ageis of the U SIG, for everyone's sake.
