This isn't really a "discussion" per se, but rather a few links that I think are awesome resources if you're into Moon phases and signs.
Has the daily phase and sign the moon is in. They also do articles on the major phases (New Moon and Full Moon) that are very interesting. They do things like Mercury retrograde and also online courses you can do.
A desktop tool that changes daily. It shows the sign of the day, the moon phase, moon mansion
(or house), sun phase, seasons, and give interesting facts about the moon. Awesome tool.
Also, another interestng thing is most of us know our sun sign, but have you found out your moon sign
Other interesting sites since I'm naming them:
Another Moon Mansion
Moon in the Zodiac
