Newly created folders give "staff" read-only permission

Question

When I create a new folder in my home directory it has the following permissions:
Me: Read & Write
staff: Read only
everyone: No Access
Other (non-admin) accounts seem to belong to staff and thus have read access to any non-standard folders in my main (admin) home directory.
1) How can I change the staff permissions on these folders (Finder gives me an error)? Is this only possible using sudo chmod?
2) How can I change the default permissions to stop giving default access to all users through the staff group?
Thx,
Chris

The easiest solution is just not to keep confidential folders that you create yourself at the top level of Home. You could instead create a single enclosing folder to hold that all that extra material, call it, say, "My Other Stuff", and put it in your Documents folder where it would be protected from all other users. You could then create descriptive subfolders within in it, which would also be protected.
If you still instead want to alter the permissions of folders that you create yourself and you don't want to use Terminal, take a look at [BatChmod|http://www.macchampion.com/arbysoft/BatchMod/Welcome.html].
