Large Domains / Non-Sailormoon Sites

Animegoddess.com
http://www.animegoddess.com
The layout just lends itself to userfriendliness.

Sweetusagi.com
http://www.sweetusagi.com
Multiple sites abound. The Sailormoon page has been rather stagnant lately, but the information there is solid and good.

General / Combination Sites

Hotoshi Doi's Sailormoon
http://www.usagi.org/~doi/smoon/
Extremely large and classically listed site. Some stuff is outdated, but for the most part this remains a standard for Sailormoon information (particularly anime-based info).

The Oracle
http://soul-hunter.com/sailormoon/
Currently the biggest Sailormoon website on the 'net. It is in-depth and comprehensive but still doesn't have quite everything up yet.

Shrines

A Three Lights Fan Page:
http://www.geocities.com/Tokyo/Teahouse/8708/index.html
It has an amazing amount of info on the Starlights, and is constructed very well and very simply. This site is currently static.

Sailor Mars Shrine
http://www.geocities.com/Tokyo/2109/mars.html
I've been to tons of shrines, believe me when I say that this one could be called ultimate. The layout is somewhat outdated now, but the content is good and more original. Things like a general profile have been written in first person to give it a new spin. The site, however, is static and has not been updated since 2000.

Miscellaneous

The Worst Sailormoon Pages Ever
http://members.tripod.com/~SailorMoonWorstOfWeb/
Though static, this site offered a bunch of information regarding the proper ways to design and execute a Sailormoon website, or any website, really. It still offers valuable info for web builders at their help desk.

Sailor Music
http://sailormusic.net
This is the largest Sailormoon music related website around. It houses the music itself, lyrics, etcetera regarding songs from all facets of Sailormoon.

Manga Style
http://mangastyle.net
This is a manga-based gallery, mostly, but it also contains things like translations to liner notes and general information about Takeuchi-sensei.
