It's clear from their forums that customer experiences vary pretty wildly. On the other hand, the CMYK vs RGB question is answered, although pretty briefly, in the FAQ. It says, in reference to full color books, "the source document and/or images should be in the original colorspace. If it was created in RGB, DO NOT convert it to CMYK and vice versa." http://www.lulu.com/en/help/book_formatting_faq#rgb_vs_cmyk I did a search in their forums for "color space RGB" and the first thread listed was a question about which RGB profile to use, sRGB or Adobe RGB. The answer from dtcampbell, Lulu Support, says, "I would recommend sRGB as the color space." I've personally never had any problems with Lulu printed products, although it's only been calendars, which are not uploaded as PDF but rather built on their system from individual JPEG (not TIFF) images.
