I second literature submissions, and character search/URL, and world galleries.
Maybe letting Worlds have a status as open/closed I guess?? *nervous sweat* Like I have a few different original stories with different characters and that way you could view them by worlds to see all who mingle together, but that way you won't be bombarded with join requests IDK I GUESS I could just have a world tag but meh. I have friends who are working on a story just the two of them, but don't want others to 'join in' cuz it's their bab, ya know? But they have characters that would be in a world, that wouldn't benefit from being open.
Also relationship trees, such as listing factions, significant others, family, friends, etc.???
this site is sick as shiet btw keep up the good work, imma spoiled brat to get to join vuv
