Hi all: As I said before, I took a few text books to validate. I've looked them over and uploaded one. However, I am having problems with the second. It was originally submitted in .doc and I converted to RTF. I then zipped it. So now the new file extension is .zip. I have never had a problem with that. However, every time I go to submit this file in .zip, it tells me it is an incorrect extension. But when I try to submit in the .rtf file, it won't upload because it's so big. Any tips? If not I'll have to release it and let someone elst give it a go. I don't know why it won't upload though as I have a DSL connection. Amber
