Sure -- we're starting in about 40 minutes (noon, US Eastern time).

Here's the content from the invite:

The main point of this meeting is to discuss 2 MPI-4 proposals that Jeff will have ready:

1. Deprecate mpif.h.  Rolf's suggestion:

MPI-3 p603, chap 17.1.4
1st para -- "mpif.h is strongly discouraged and may be deprecated..."
  --> change to "is deprecated and may be deleted..."
  --> Add (short) AtoU, if you have software using mpif.h, you should
      change it thusly...  (see page 603 line 15-17 for

2. Freeze the mpi module (no new features).  The intent is to focus all of our energies on the mpi_f08 module in the future.  If there is push back on this from the Forum, our plan B for this is to modernize the mpi module (i.e., add all the features to the mpi module that we added to the mpi_f08 module).  Rolf's suggestions:

 --> Add AtoU encourage users to move to mpi_f08
