Just thought I would mention that not only do names have too deep an importance to allow some game to determine them within my tradition, the vague numerological system used is rather alien.
I suppose the real issue here is the disrespect to other traditions that the OP showed. What they think is "fun", many may find insulting since it insinuates that the traditions we draw from aren't relevant.
This was something I was hoping she would stick around long enough for me to get into. For the most part, my culture provides names for its people in ways that are recognized by the community. My spirituality, though not necessarily mainstream for that community, urges me to recognize my part in that community. I think, on the part of my Gods, should I present myself with a new name suddenly, there would be some raised eyebrows.
Though, secret names in a religious context are probably a different story, and not one I have too much experience with.
Either way, in my case, the numerological system has very little bearing and would be irresponsible of me to rely on it for something as binding as a name.
