Just one Category?

I have not found a set of rules for discussion, nor a set of categories for discussion, or even whether discussion is to be limited to only The writings of Noel Tyl.  While Noel wrote 40+ books(and some of them he actually sent to me with inscriptions), there are many stuff of astrology that were not central or even included in his astrological cosmology.  I do not know if those other subjects, such as asteroids(which I think he added to keep me from posting it in the main forum 😉 ) or Arabic parts, or Astrodynes, etc. are allowed to be included here.
