A whole bunch of accounts that were deleted in the past two years were recently purged (including marikochan, one of the very first accounts I friended *snif*). This means, among other things, that it is now possible to rename your journal to one of those names.
Also, there'll be a Permanent Account Sale on sometime in June: for the low, low price of US$ 150, you can have a Permanent Account. Or two or three, if that's your thing. (Disclaimer: price may not actually be low, depending on your disposable income.)
