Jeff has been around the community for years. I don't think he is a current member of ITA but his photo in Linked In is really familiar. I know I have talked with him at Sage conferences and he may have been a member of SLA at one time.
I don't have a personal relationship with him. I will reach out to a few friends at ITA and in the Seattle area for input. However, at this point in time, I would support is admission to the group.
