Uh, Pete, You say:

I recently went through my freight car photos and sorted them into two separate albums, pre and post 2000.

The STMFC rules clearly state:

"The objectives
include the sharing of
information about North American, standard gauge railroad freight cars in
the period 1900-1960 inclusive..."

There are groups that cover time periods after those of the STMFC.
