Query: The lack of a table of contents makes this unusable

This magazine has no table of contents. And when I downloaded my first edition, I wasn't even positioned at the first story. There's no way to tell what the stories are, how many, or how to get to them other than to page through hundreds of pages. It's a shame, because the content looks quite good - but without a table of contents this is UNUSABLE! I'm glad it was only a trial subscription. A word to the publisher - get a clue!
