I searched to see if ther were threads on this topic... but I couldn't really find anything.
Does ANYONE know how to override the default layout on LiveJournal?? I don't want to use the ones they provide, but a simpler one. If you could help that would be EXCELLENT.

LJ does have an FAQ (http://www.livejournal.com/support/faq.bml) section... this one (http://www.livejournal.com/support/faqbrowse.bml?faqcat=customize) specifically deals with customization. To completely override it, and make a new style, you need to have a paid account or be an early adopter.
