This tool will help you unsubscribe from mailing lists of any type. All you need to know is your network ID, and the mailing address of the list. It's a good idea to clean up your files and mail folders now, instead of waiting until fall. By then you might have forgotten where things are in your accounts, and you'll spend twice as much time figuring out which things are safe to delete. It's especially important while you're away that your account has a good password.
Crackers often use dictionaries to try to crack passwords and break into computer accounts.
So make sure that your password is something that you won't forget over the summer, but that's not an easily-guessed word. If you do forget your password over the summer, you can get it changed when you get back to campus by bringing your photo ID in person to the UCS Support Center, IMU M084. If you're leaving IU for good, you should still clear out your accounts and unsubscribe from mailing lists. If you have shareware software and have paid the shareware fees, you can probably keep that software. One final thing.
