Hi René,

The latest coding was done with version 4.5.3. I have not merged my git 
repository with GROMACS for quite a while (the last time I tried somethings did 
not work). I will send a link with the updated and merged git repository as soon 
as possible, probably by monday.

I will try to keep the code as clean as possible (with few modifications to MD 
code), which also means it wont be as fast as it could. I would love if someone 
could take a look at the code and see if it could be easily integrated with the 
official version.

I totally agree with the specialized discussion groups.

Nice work André!
What version of gromacs are you working with? (if I remmeber correctly, it was 
I'd be happy to make the GCMC module compatible with that version as well as 
make it compatible for the latest version of gmx. Keep in mind that for now it 
only works for the LJ system, but it's the first step towards GCMC with 'real' 

I agree with Michael that it would be a good idea to have a separate discussion 
group for more specialized stuff. I have no idea how many people are interested 
in gmx-mc? If the interest is too low, a separate discussion group could be
