On my business directory (I guess like many others), users sign up, log on and can list their businesses. The information they provide when they sing up doesn't neccesarly have to be the same as the ones they provide in the listing (i.e. name and email address).
Now, if I as the administrator need to contact the owner of one of these listings I have no way find out which user listed that specific listing. My information is one-way go only, which is from a user I can track all his listings, but from a listing I don't know how to find out the owner of the listing (well, unless I go through every user's listings one by one which is unreasonable).
Am I making sense?
