Last week I shared a detailed list of my local (Texas and Louisiana) opportunities which can still be found here.
I promised to return this week with a more detailed list and information about nation wide options. However, I found this great list on Jodie Renner's blog and thought I'd pass it along as it's more detailed than the one I have.
I still haven't done any research on international opportunities for this year. If you know of any, or would like for me to add some to the other two lists, please let us know by leaving a comment.
