You do not have to be that polite on this list. A simple Hi or Dear
DUNE developer is enough.

BUT: Please make sure that your full name is _always_ included in the
from header of your email.

Sounds like a perfect start.

The way it works is as follows:

In the subversion repository we will create a feature branch where you
will implement your changes. At the beginning this will be just a copy
of the trunk. After your implmentation it will still provide the
features of the trunk but additionally provide the inserter
algorithms/classes. So there is no need to reimplement the wheel.

IMHO this is the main advantage of Open Source or free
software. It is free as in freedom. You can just look into the code
and add additional functionality that you need or pay someone to due it.

In contrast, if you are using proprietary or closed software, than you
are at the mercy of the corporate. Usually it is very unlikely that
they share your need for a specific feature and will add it for you.

I hope I could help!

Cheers,

Markus
