So it's not easy to have only one way to describe various cases, but I think that

the field names in our relation table are clear enough.

well in any case, i made the tbl_relation.php3 after we changed the names the last time in the hope that people would be able to stop wondering about which column means what. But this doesn't work for him as well, so i hope that when we are able to help him use that he can ignore the column names we choose as well ;-)
