Garasu no Kamen Forum

I am afraid I do not have the time to admin/moderate a forum of my own, but this site is affiliated with the forum:

Murasaki no Bara no Yume.

It's in Italian but it contains an English section. Everybody is very kind and friendly.

I also recommend the following forums:

Shoujo Manga Outline (Italian)

Il Grande Sogno di Maya Fans Forum (Italian)

Glass Mask Forum (English)

Glass no Kamen: Forum (French)
