A story published here by Shemmelle in 1999-2000 has been republished at a big fanfiction site by a user named "KittyBennetFanficCollector."
While Shemmelle is credited it's not clear this person has permission to republish this work, especially at a commercial site supported by advertising from which authors receive no benefit.
I haven't seen anything by/about Shemmelle in +10 years, have no idea how to contact them about this situation that may constitute intellectual property theft.
If you have published any JAFF in which Kitty Bennet is a lead character, keep your eyes peeled for similar "borrowing."
