Guys i dont want to "abuse" from your help , but in my case im using this to save list's with favorites but 1 member can have more than 1 list. So when they want to create another list, i need to create a new property to the member? I already created "myList1-Foundations" but if the user wants to create(and he have that option) "myList2-Foundations" i have to create dynamicly the property ? how? :S

 In the backoffice is something like this : Name is normal textstring, Fondations is type autocomplete from ucomponents. And im using umbraco v6

Thanks for the effort and sorry for my bad english (im from Portugal :D)
