Hello, i am trying to find the same sort of things.  :).   When you say user, do you mean members?  What are you trying to do, i have had some success.

@Charlie,

No, I'm referring to backend users. I have it working, but I just get a notification when using CMSNode that it is obsolute and will be removed from the source eventually. But since umbraco.BusinessLogic.Permission requires a CMSNode object, I'm wondering if there's a newer Permission API I should be using. The current code is actually really simple:

// get the user object for the user's permissions you'd like to change
User u = new User("username");
// pass in the Id of the target node and set the ideal permissions
Permission.UpdateCruds(u, new CMSNode(targetNodeId), ":CMF");

Hi, everything has moved to the ASP. membership provider rather than using the umbraco api i believe for this sort of thing.  So you need to the User.Current() out of the HttpContext.Current.

Additonally umbraco.BusinessLogic.User has helper methods.  Not sure if they are any use for what you are doing though.

I was looking at the members rather than users.
