Several ebooks and titles
I want to publish my book in three formats: print, EPUB ebook, and PDF ebook.
For my convenience I want the titles of the book show differently for each of the three versions of my book in author's dashboard ( http://www.lulu.com/author/ ).
But if I change ebooks title from "New Testament Commentary By a Mathematician" to "New Testament Commentary By a Mathematician (PDF)", it says:
This title does not meet Lulu's capitalization requirements.
Please help me to organize my several versions of this book.
