International Positions – How to Include in Caucus Board?

We are looking for grad students to please help us consider the possibility of integrating floating international positions to the NASSR Grad Caucus executive board? I know that the Canadian spots should surely remain, but I would be interested to know how we can include our colleagues from nations other than the US or Canada. Jeff Cox threw out the idea of the floating positions to ensure that candidates from anywhere in the globe could contribute and help us to keep a diverse course. Thoughts? Ideas? Concerns?
Please respond with comments – many thanks for your input.
