Well, thanks to the new groups interface we can have more than one thread in every group so it'll be pretty easy to have the fan group cleaned and updated.
As the main theme of the group I think this theme can be quite interesting as a test to know the tastes of all members of the fangroup, it would be as well usefull to post the name, the anime title and a link to a picture of the loli, this way we'll also create a little database of "Anime with lolis" ^^
Of course, my favourite loli is
Rin-chan from the anime
Kodomo no jikan (
Child's time)
