The Sailor Moon channel website updated on September 1st.

On the top-left of the main page, the scrolling text says:

Fall has come quickly upon us. I hope no one is catching a cold. We've updated the mailbox and added Sailor Pluto's profile. For anyone who hasn't played the latest Game Center Crown game, what are you waiting for? 

As the note says, the two updates include the mailbox page and the addition of Sailor Pluto to the album page. It's just a brief profile with her favourite color and such.

Here is the mailbox update, which is listed as 8/1 for some reason.

From Sayarin-chan (Age 10)

I love Usagi-chan! Please continue to punish the Dark Kingdom in the name of the moon, and save the world! I'm rooting for you!

Luna: Thanks for your support! We're doing our very best, so Sayarin-chan, please help us protect the world too!

From Risa-chan (Age 9)

Usagi-chan seems to love ice cream, and I too love ice cream, moreso than sweets. I won't give up!

Luna: Actually, Usagi-chan likes ice cream but, she loves, loves, LOVES, sweets too! Sweet stuff is the best! But don't eat too much of it!
 
From Fearii Earii-san (Age 18)

By chance, I've recently come to love Sailor Moon. Every night I watch the Sailor Moon television series! I've bought the tankoubon too! Sailor Moon is a godly anime!!
  
Luna: Thank you. It seems you've just lately come to appreciate Sailor Moon. We plan to continue to introduce the activities of the sailor senshi at this homepage, so please look forward to it.
 
From Fubami-chan (Age 9)

What's a crescent moon shale?

Luna: I think you're asking about the lyric from the Sailor Moon S ending theme. A shale is a glass dish used in science experiments. If you make one in the shape of a crescent moon, I think it'll be sparkly and beautiful.
  
From Rii-chan (Age 8)

I've loved Sailor Moon since I was three years old. In particular, I love Usagi-chan! I won't forgive anyone who bullies Usagi-chan!
  
Luna: Rii-chan, thank you! With your support, Usagi's courage has gone up 100x! We'll keep fighting our best, so keep watching us!
  
From 'Playful Rabbit' (Age 13)
 
In the Black Moon storyline, when Chibiusa fell, it looked like Usagi's neck was in a lot of pain. Was Usagi okay? Last, I really love everyone!

Luna: Chibiusa is pretty light so I think it was okay. But Usagi said that she was really surprised.
