I'm preparing to import Roles (and eventually Users) from another web site into DNN. The source web site has its own custom security tables, and are somewhat similar to the tables found in DNN. However, the "somewhat" part is what I'm wrestling with at the  moment. I see a table in DNN called RoleSettings, which seems to allow for a Key/Value pair, and I'm assuming this is for custom properties for a Role. I'm thinking that I could use this table as a place to store some of the columns that are found in my source security database 
that have no direct mapping to DNN. However, I see no usages of the table "RoleSettings" in my default installation of DNN 6.2.2. Can someone point me in the direction of a module that would populate this table, or some documentation on where it's used?

Thanks,

Chuck
