Possibly adding Password

Just a heads up... I have removed a few posts (for now)and I am trying to figure out a way to add a password just in case. If you know how I can do that besides going to wordpress, please let me know. I do not want the entire blog password protected, just certain times with a certain someone. ;-) If I need to do the whole thing, I will give a shout out before I pull it. Might just start a 2nd blog for those posts. Things are fine, no worries.
