Took me a few days (with my girlfriend needing to use the computer for myFace) but I churned out a -very- basic astrology script for zMUD. It checks date and requires a watch (I've seen them as cheap as 2k.) It's customised for me, including the gags and alias-hints but those can be adjusted if you can script at all in zmud (just adjusting the #gag and deleting the echos.) Commands are STARS to see simple stargaze (without an astrolabe but WITH A WATCH) and DOSPHERES to see positive and negative spheres. No costs shown, from minor to major affect (or should be.) Let me know in-game about some bugs (since I'll need to adjust as well.) Mind you this won't show affs of any sort but once you use astrology for a while you tend to memorize what does what anyways. Enjoy.

Completely off-topic but....Izekeal make a ZMUD system!
