carlspanks:
I think she did all, but possibly tended more to FM and MM stories?
When I first stated reading her stories on the soc.sexuality.newsgroup, Julie (Julnick) was writing primarily F/M accounts--my favorite of hers was "Into the Woods"--but several years later she shifted (disappointingly for me personally) to M/M ones.
The last I read online concerning Julie, she had stopped producing spanking-oriented material altogether--that was in the mid-2000s...
