Hello Community,

It's been awhile since a Community Newsletter has gone out, but no longer.

support you and grow our community.

have a long history working with technology including development, 
architecture, administration, ops, and training, so I look forward to working 
with you, in whatever role you serve, to make your adoption of MarkLogic easier 
and maybe even fun. We want to hear from you about what works well and how we 
can better serve our community, so please don't hesitate to reach 

Dave Cassel has shifted to a role in the Engineering department, returning his 
focus to developing software. He remains active on Stack Overflow and will 
continue to participate in MarkLogic World and Meetups when he can.
