Has anybody used the Relation module [http://drupal.org/project/Relation] and be willing to share set up tips?
I have an acquaintance in Traverse City area that is working on seed saving site that requires farms to be able to register seeds and other farms to select and list any registered seeds (general jest from a quick conversation).

He is having trouble setting up the Relation module and would like some tips for this. I haven't used this module yet, so was wondering if anyone might give him some suggestions.
FYI - He said that he has gone through the tutorials.
