can I give one user more than one level?

is it possible to give one user more than one user level?
or when he login can select the user level from a list box of the given levels?
is there any way to do it?
thanks in advanced.

To change/add user level, please read help file topic: Server Events and Client Scripts → UserLevel_Loaded / TablePermission_Loading / TablePermission_Loaded.

thank you

Alternatively, you may create a new user level which has permission that combined from some existing user levels, and then assign that new user level to your end-users.

thank you
i did that working good.
