Yes, I most definitely recognize your nickname and have been a beneficiary of many of your answers, blog posts, etc. Glad to hear you're interested in participating. You've been prolific on the lists and I'm wondering if you have a top 5 olap items that you see people have trouble with over and over? A brief presentation of your responses and pointers to what you've already written would probably be very helpful for folks who are attempting the Spark path.

Thanks,

Ted
