"As a side note: just to let you know, I'm really happy to be working with RidgeRun in general. It's pretty clear that you tell it like you see it, and know what you do and don't know; it's really refreshing. That's super rare on these kinds of technical engagements when everyone seems to either want to claim expertise they don't have, or are so cautious they are don't actually say anything useful"
