Regardless of everything else: are you interested in registering as ET
users: http://einsteintoolkit.org/about/members/ ?

Please contact me directly for user accounts. You will need them to
upload anything to the ET SVN, even to the 'incoming sandbox'.

The Einstein Toolkit does not contain this code. If it would, it would
be publicly available. As already mentioned, contributing to the
Einstein Toolkit does not mean to get access to some other code in
return. What you do get is acknowledgment and respect. Besides that, you
get more eyes on your code: a good thing because in the long run because
it means fewer errors and shared maintenance and porting work.

I would suggest to start this slowly. I am always happy to see
contributions to the toolkit. The way this usually is handled is to make
the code publicly available first. If you don't have a convenient way to
do that we do provide one just for that purpose. With the code
available, people have a better ground for discussion.

After especially the maintainers had a chance to look at the code they
will decide about the inclusion into the ET, and quite often request or
make changes before that.
