Hi,

i try to store objects which differ through a complicated  
relationship.  
So e.g. i want to store the moderators, the user … of another  
object.  
Currently i create an array for each relationship where i store the  
users with this particular relationship (@members\_users,  
@members\_moderators, …).  
I think thats not the best way, so can i add a custom attribute just  
for this case and not in the db to differ between the different  
relationships and that i can store all members in one array?  
Do you’ve got another idea to handle this situation?
