Pretty sure we can't order then right now. The admins haven't focused too much on the links feature in the past but I think that I've heard they plan on working on it in the fure. Ordering them around would indeed be a really nice idea!
I don't know if it's the good forum but whatever.
I'm pretty new with links for charas, and was wondering, it is possible to change the order of characters linked ? For example, i want the link of my character with their mother is shown before the one with their brother, but i uploaded the brother before the mother, how should i do for it's showed ?
