I recently replaced the drive in my Macbook, upgrading to a larger capacity drive. For the first time I used Time Machine to restore my applications, settings and data files. I was surprised to find that I had to name the restoration differently than the account named on the destination drive. I followed the on-screen prompts and successfully transferred the data from my old drive to the new one.

Is there a way to RESTRICT joining certain wifi networks to certain OS X user accounts?
When using my MacBook Pro, I have two basic OS X logins. One for known SECURE wifi networks, and one for INSECURE wifi networks. The problem is that Airport settings always remember the INSECURE network, and almost always tries to connect my SECURE OSX login to the INSECURE wifi, at which point Mail (or other apps) start up and shoot my logs/passes across the air for all to see.
