Just used CHCR's suggested acronym link for the first time, Manti, to outcheck yr "imo."
Yr reasoning makes sense to me and meshes with my desire to add: Think I'll go back in for a little dip. A week or so ago, belatedly trying to explain my participation here, I said I'd waded into ERCH-E up to my knees. Well, I'm now up to mid-thighs!
Thank you,
