If you don't mind reading stuff on a computer, then I'd suggest just googling for tutorials online. While they might not be as structured as a book, end to end, they generally give more tips / tricks, as well as cover a wider variety of topics.
There are some very structured tutorials out there btw.
I "read" or begun reading a couple of those, for Photoshop and InDesign, and generaly they go over sooo much information and I dear to say you are wasting 3/4 of your time even if your completely new to the program. Do as Moridin said, read guides, tips and tutorials made by "un-professionals" (typicaly they know more about the program than the creators do).
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
