Okay, the official list as of now is the following:
Lurkette|Lurker (1)
Browsette|Browser (10)
Regular Girl|Regular Guy (45)
Lady of Fukufics|Lord of Fukufics (200)
Asteroid Senshi (500)
Moon Senshi (1,000)
Prism Power Senshi (2,000)
Crystal Power Senshi (4,000)
Cosmic Power Senshi (6,000)
Crisis Power Senshi (10,000)
Super Power Senshi (20,000)
Eternal Power Senshi (40,000)
Moon Princess (60,000)
Moon Queen (80,000)
Empress of the Moon (100,000)
The first four rank titles may be changed later to match the theme, but the goals to reach them will not.
Crescent Pulsar mentioned elements like Ginzuishou, sailor Chaos, and chibi chibi crystal power. While "Chibi Senshi" might work as a replacement for Lady/Lord of Fukufics, I can't quite see how the others might fit in. Any suggestions for the first four ranks?
