Not everything is consistent because some of these guidelines have evolved and I've been too lazy to write a script to change everything. Titles of music albums and songs, articles, movies, books, comics, and TV shows are all italicised when used as part of continuous text.
Exceptions are when they're used in headers, or in an itemised list by themselves.
Words in titles are generally capitalised except for certain un-important words. Words in article titles are not capitalised except for important words. Titles will be consistent with the intent of the originator of the title. Signatures include a link back to the main theme page. If users want to go back to the page they were last at, they can use the back button.
