  OK, both Shuhua and Eileen mentioned this commenting / tagboard service to me so I thought I'd check them out. I've just attached the relevant commenting feature into each posts. Anyone with any comments can now feedback to me anytime. I'm still not sure how I'd like it but whatever the case, I think I'll just try it out until it becomes too much of a chore or interferes with what I'm doing. Happy reading.
