A friend of mine received a request from a man currently in prison (letter was stamped: Inmate Mail. Department of Corrections). The work is not his area of specialty, so he forwarded the request to me. Unfortunately, I have no PO box I could use, and the man has no access to email, it seems. Any other ideas so I do not give out my personal address? Any precautions you may offer? I have worked within prisons and for inmates before on other types of projects, but my information was always kept private, and I was paid by an agency. If I went ahead and accepted this project, it would not be for the monetary gain, it so happens that the research sounds interesting, and it would be relatively difficult for him to find someone else to do the work. Suggestions welcome.
