Precautions
Perhaps all this is already stated in my Lectures, but I'll spell them out anyway. Many people who like Pokemon are victims of hazing and the sort, and many of them do not know how to protect their Xangas. It's actually very easy, once you think of it, as Xanga has given us the ability to ban members that are insulting us. If someone leaves a scathing comment on a post, just click on the "block user", and they won't be able to bother you again.
The chatterbox is different, but not by much. You can't ban people off your chatterbox, as far as I know, but you can put certain codes to control who posts on you Xanga. For example, on the PA homepage, the chatterbox requires you to sign into Xanga in order to post. If you're a hater, then you would be opening the floodgates to the entire army, which isn't smart (though many haters rarely display that trait anyway). The code can be found online, or you can save yourself the big look and search here.
