My question: Is it possible to reference a field to a node, and also to a user?
I want to keep track of scores scored by users while playing a boardgame. So, I'll need a reference between nodes (boardgame) and users. I'm using the "entity reference" for this.
With the module field_group and field_group_multiple, I can make rows with user field, score field, etc... But the problem here is: the score field is linked to the node, not to the user. (So if I want to make a view and get all scores scored by a player, this will be not possible.)
