Hi John and welcome to MR.
I went to your site (I missed your previous posts) and tried to download epub for my Sony 505. It opens to a page of... well, I don't know what.... it is a page of symbols and numbers.
I don't know what tagged pdf is. I tried one download of that and it opened on my computer. Before I try it on my 505 do you know if it would work without freezing my Reader?
Also, if you need help in converting, offering other formats, or just need someone to test the formats, just ask and one of the members will jump in to help.
P.S. You might want to post in the Writers Corner and / or the Deals, Freebies, and Resources forums. You would be able to attract more attention in those forums for your work. (It took me a bit to locate your post again as I assumed I saw it in the other 2 forums..)
Thank you for offering your work to us. We are always appreciative of writers who are willing to learn about ebook formatting.
