Guy:
Hand's down, the greatest "one hit wonder" in the library is Placid. Her/his story "Accepting the Unfair", with over 2000 views and 61 comments, sits near the top of the 'stats, yet it's that author's sole contribution to the library.
I would certainly like to see more stories from Placid.
As it turns out, there are few more of them in the soc.sexuality.spanking archives that you can find on Google Groups, including:
Resolving Differences (M/ff)
Should Have Said (M/F)
Boss Comes to Dinner (M/F)
Simple Games (M/F)
