    Can we just ban them all together? I know they help "fix" errors in the stellar models; but they aren't accurate for highly reddened regions and I find them a barrier to physical understanding and improving the models!

    Perhaps also that the meeting is so big, it is hard to know everything that is going on! There seem to be so many special sessions, evening sessions, a wider diversity of topics. All good; but pulling us in many different directions.
