Excellent suggestion, Mags, as usual!
I thought we might have a style page recommending this, but I don't see one. It has been informally recommended.
I think a Research Notes section is an excellent way to encourage collaboration. If someone can complete the research or answer the outstanding questions, the notes should definitely be cleared as the work is completed.
By the way, RJ, I apologize if this sounds pedantic -- it's a pet peeve -- but a profile is never really "yours" or "mine."
