Just an update on this tool for people interested and also because I am off to New York for a few days :-)
I got laughed at by a good friend of mine due to its boring name so I had a think and now call the tool SPUM2003 Along the lines of SPIN/SPOUT for SharePoint. Well, that is my rationale for choosing the name.
I have done some more work and now the code operates on WSS site security by Adding, Deleting and Editing users and then displays their details, Alerts, Groups, Cross-Site groups. I have started to make the UI look a bit better and also in the process of enabling Site Group editing/management. Haven't got the SPS Area security bit working but it will shortly.
