Interest: Definitely interested! A for-sure answer will obviously depend on how things look for me when it comes around. I love a good identity crisis.
Location: No preferences re: location.
Anything else: The first two respondents here both had good points about echo acquisition that I agree with (even things out for LCWs, loosen up the process for memory-only echoes). A hard cap on echoes per month that's known from the beginning sounds like a great idea, too, since it'll help everyone figure out how to pace things.
