[CQ-Contest] sending DX QSLs from US other than via ARRL service

[James Cain]

I stand corrected! From "Introducing Logbook of the World":

As stated in LoTW's Mission and Objectives, membership in the ARRL is not a requirement. 

My excuse is that I've been an ARRL life member since 1972 so I didn't give membership a thought.
