When you are about to delete one or more accounts in Notes, you select the user(s) to delete, then you click the button Delete Person. You get a verification message. If you click ok, you get a Delete User Options dialog. The last dialog is if you want to execute the delete immediately or via the admin process. Lastly, you get a Success message. Somewhere in the process, maybe at the first one, there should be a list of names of the accounts you are about to delete. I'm sure I'm not the only one who accidentally selected a user who you did not intend to delete but didn't realized it was selected until it was too late. It could be a dialog that says something like: "you are about to delete the following accounts: <list them>. Do you want to continue?"
