I can say wtf in here because it's MY space. If I were walking around Preston I might get arrested for saying wtf apparently. 
Also I could be fined if I spit in the street. This blog doesn't give me the option to spit, which is just as well, because none of the other options, including 'set options' seem to work. In fact 'set options' allows me to write a bit of blurb to appear above the 'set options' link. But not to set my options. Heaven knows what would happen if there was a 'spit now' button! I degress. My wtf for today is: why do I need to set the 'who can read this' for each individual message instead of the whole blog?
