Even excluding the Martina from TTS, the situation can be confusing.
A long time ago at JandMStars was a Martina (Snytova). I think she is the one in the name JandM; the other being Jitka. Later on she left or something, and is now with Jitka and Lucie at JLMtopstars. The Martina in this thread is the Martina currently at JandMStars. :]
I ran into this quirk when I was looking up Martina of JandM and found a different Martina of JandM... :P
Some people might not care, but it is hell for a collector... sigh
