[gmx-developers] MC with GROMACS

[Shirts, Michael (mrs5pt)]

So, this reminds me about having separate focused discussion groups on
important general topics for future and current development in Gromacs like
Monte Carlo and free energy calculations.  How are any plans for this going
right now?  It would be a shame if potentially good contributions like this
ended up not being incorporated because they were written in a way that made
it hard to integrate in, or if multiple people are working independently on
the same functionality in an incompatible way.

I'm willing to moderate a free energy calculation group.  It can be as
simple as a separate gmx-XXXXX at gromacs.org mailing address, and wouldn't
necessarily need to be publically indexed.    How difficult would this be to
set up?

Best,
