JewishGen has two databases of communities:
1) The JewishGen Communities database with a listing of over 6,000 communites with known Jewish communities
2) The JewishGen Gazetteer based on the US Board on Geographic Names databases for 54 countries in Europe, North Africa, and the Middle East.You can see more about these resources at http://www.jewishgen.org/databases/
I wish that there were a way to connect the databases so that in RootsMagic I could use the County Check procedures with these established JewishGen European databases.
I am a member of JewishGen (a non profit), and a user of RootsMagic, but not an officer of either organization. I am also not a professional programmer. However, if there were some sort of freely available parameters, I would be willing to look for volunteers to help with this project.

PS If it is reasonable to begin this project within a year, it would be wonderful to have RootsMagic present at the International Association of Jewish Genealogy Societies Conference in Bosotn on August 4-9, 2013. Calls for papers are due January 6.
