I can appreciate the size of paper issue, however some users like myself do not have iPads nor Apple products. This makes use of an epub format more challenging.
Thank you for the response.
ePub isn't an Apple format? — it's a cross-platform ebook publishing industry standard, originally in competition with and now adopted by Amazon's Kindle. Ebook reading software for literally any platform should support it.
I should also point out that I am willing to meet people halfway on formats, but I'm not prepared to waste effort on a PDF for you that might just be unreadable — and you haven't told me anything about the screen you want to read it on.
