Mainly we want to avoid exhausting the attention span of Public Lab folks who are not that interested in spectrometry, and not have to feel worried about actually *having* really long spectrometry conversations. This is kind of like how "
grassroo...@googlegroups.com" is mainly for balloon/kite mapping, and overlap with the main list is OK. I'll be a little annoying fwding things back and forth for the next week or so, and I'll also send specific invitations to folks who have been very spectro-active.
