Colby set up a wiki for us to use for documentation at http://docs.einsteintoolkit.org/. The hope is that this will gradually get filled out by those of us using the toolkit, and it will be a better way to keep the documentation up to date. Also, it might help target the documentation on what is really wanted, rather than trying to guess what would be useful.
At the moment people need to get a login with us to edit the wiki. We also wanted to have a more anonymous and easy-to-use login, but are we still arguing about what this should look like and if we will get immediately vandalized.
