Warp My Mind!? Safe? Fun? Anyone use it/try it?

Now being someone that is into bdsm, some of the things I read there, does seem attractive to me, but hypnosis is totally new to me, and the possibility of life long subjection, though appeals to me, may be somewhat inappropriate say for example, at work, college etc, so here's the question, should I be messing with things I don't really understand, how 'trustworthy' are the files, after all they could slip in something we don't know about. anyone used the Site, if so, tell me about your experiences?

Sorry for the long spiel, thanks for your time :)
