this doesn't break the module or anything, so i'm listing it as a feature request rather than a bug.

in the editing area for article A, i've assigned articles B and C as being related. but when editing article B or C, article A does not show up as related... so the relationship is only one-way, rather than mutual. this also shows up when working with output of related items: when viewing the related items for article B, i only see its "parent", article A. it seems to me that defining a "relationship" should be commutative.
