IllinoisGRMHD robustness:
* Zach reduced the maximum allowed speed to have a max. speed less than
* finds that robustness is greatly increased if one uses 3rd order
  Lagrange interpolator for IllinoisGRMHD variables. There is a pull
  request for such an operator:

* remove MPG machines: draco, minerva, hydra are MPG machines. Wolfgang
  said he could maybe run on one of them, if not then we will remove
* Peter will run smic
* Marconi: a machine in Italy, Roberto de Pietri, Eloisa had access, if
  they cannot run, then we should remove them

Moving website to github:
* may be difficult to move due to multiple repos being linked up
* some pages use php and cgi which are not straightfoward to run from
* currently have docker image that makes the server much more
  self-contained than before, docker image is here:
