Man Behind the Mask - Heather runs this fabulous Duo Maxwell shrine! Tons of information, images and fandom and relationship thoughts. And her layouts are always great.
The GWG - Du runs this awesome GW site. Definitely go check it out. Because great GW sites are hard to find these days, and you don't want to miss this one.
Faraway Dawn - Noin's Zechs' shrine is probably the coolest Zechs shrine I've ever seen in my life. Not only do her layouts make me stare in awe, but she has great Zechs info and images, tons of things to do, and a darned good site name.
Intergalactic - If you think you remember Chelsea, you do - she used to run the awesome HXR site, Smitten. Smitten is longer around, but DEFINITELY check out Intergalactic, a Heero site with one trendy, awesome layout and lots of content.
Afterglow - Chelsea's other awesome GW site is Afterglow, with a beautiful layout and great Relena information. The perfect compliment to Intergalactic!
The Official Milliardo Peacecraft Fanlisting Site - Lilly was an old affiliate of mine way back when I was into fanlistings. Her awesome Zechs fanlisting must be visited. Not only can you join if you're a Zechs fan, but she's working on getting plenty of great Zechs info there, too! Go look. Her layout is to die for.
Obsessed Fangirls of Duo Maxwell - If you're a Duo fan and you haven't seen Rebecca's OFDM...where have you been?? Go look. Just go look. She's got one awesome Duo site - with even more images of Duo than I have! And that's saying a LOT, since I have over 160.
The Shade - Kaika Rei maintains this awesome GW site, which is now back online and more awesome than ever! Definitely go check it out!
In Rose - Li hosts this gorgeous GW site (currently on hiatus).
Domain of an Angel - Sora maintains this cool Quatre/Gundam Wing site (currently on hiatus).
