Dr. Parker,

I had found some good online resources for Fortran, and I thought if you wanted to add them to your website as a link or something along those lines:

Michigan Tech University has a pretty good Fortran 90 tutorial available below:

For those wanting to (re)learn Fortran and have examples of a lot of different things you can do, the following is a good lecture series (start with #5) about Fortran 90 from Penn State:
