Done... http://wiki.gromacs.org/index.php/Membrane_Simulations
Someone who actually does this sort of simulation should check it over
and expand as appropriate. Chris? Tsjerk?
Mark
Looks great. Thanks Mark. The combination of a wiki with a mailing list is certainly benificial. I'll add to it as I have the time and as questions come up on the list.
Chris.
