I was recently asked about alternative uses of OJS and decided to hunt around to see what I could find. The results were quite interesting, with OJS being used in a number of unexpected ways. Here are some examples:

1. Student journal: http://www.librarystudentjournal.org/
2. Teaching tool: http://ejournal.vudat.msu.edu/
3. Book archive: http://journals.sfu.ca/coactionbks/
4: NGO Newsletter: http://www.americanmorrisnews.org/
5: Genealogy: http://www.genlit.org/
6. Annual Reports: http://ojs.iucaa.ernet.in/index.php/annual
7. Staff Publication: http://researchnews.athabascau.ca/index.php/research-news

If you have some examples of non-journal uses of OJS, I'd very much like to hear about it.
