+
+------------
+
+1) Confirm quorum
+
+Quorum is present.
+
+2) Secretary
+
+Secretary is Jeff Lait.
+
+3) PR 1626
+
+Legit and will approve.  This is a new prime number choice for the
+hash.
+
+4) OpenVDB Course
+
+Plan is to submit lecture notes after course.  But last week got an email
+suggesting we haven't submitted any thing.  Will refer back to that
+conversation.
+
+We could shorten Ken's intro too.  This depends on number of people.  Fifteen
+minutes per person.
+
+Dan wishes to discuss Explicit Template instantiation.
+
+We probably need an introduction that covers internal nodes.
+
+How to split it up for developers vs users?
+
+Jeff B and Greg Hurst are user facing (Houdini and Mathematica).  Others are
+more low-level developer.  Greg Karr for topology edits on GPU.  
+
+Do we have a present, future, and users?
+
+Andre will add to the examples directory the smoke solver & flip solver.
+Where should the examples live?  In the openvdb/openvdb/examples?   Or off the 
+base level?  The latter allows AX to be integrated, but we may not want AX for
+a lean example.
+
+5) Releases
+
+We need a 10.1 before we branch to 11, aiming around September.  There
+is a big NanoVDB dump incoming.
+
+6) Multiresolution
+
+Technical document and repo is availble for discussing.   We should read and
+then ask questions about it.  NanoVTT to be a grid-based multi-res system.
+Unlike VDB, this has a meaning: Voxel Tile Trees.  
+
+Is VTT an intrinsically different structure, or a variation of VDB?
+
+7) Next meeting
+
+Next meeting is on July 11th, 2023. 2pm-3pm EDT.
