[petsc-dev] Prediscusion of appropriate communication tool for discussion of PETSc 4 aka the Grand Refactorization

[Barry Smith]

   I'd like to start a discussion of PETSc 4.0 aka the Grand Refactorization but to have that discussion we need to discuss what tool to use for that discussion. 

   So this discussion is not about PETSc 4.0, please don't discuss it here.

   What do people recommend to use for the discussion

      * dedicated mailing list
      * slack channel(s)
      * zulip channel(s)
      * something else?

  I'd like a single tool that anyone can join at any time, see the full history, can attach files, search, not cost more money the we are already paying, etc.

  I expect this discussion to take maybe a week and then the actual discussion to take on the order of two months.

   Thanks

     Barry
