In the third paragraph, it reads, You may choose from Public, Private, Friends, and Custom. I think a sentence should be added like, "Please notice that the "Custom" option will not appear if you have not defined any Custom Friends groups. Please see http://www.livejournal.com/support/faqbrowse.bml?faqid=102 about this." Additionally, I think what comes right after that (about making one's entire journal friends-only) should have its own paragraph.
Then, further down, under the "CUSTOM:" heading, perhaps this sentence about the option not appearing if you don't have any groups defined, should be repeated.
