I am always on the look out for useful websites for my guests and came across this one which is brilliant for serious students of hieroglyphics. http://pyramidtextsonline.com/tools.html
For those of you just starting this is the book recommended on the Manchester University course that I did. I think it explains it really well and uses a local tomb Ankhtifi at Moalla. So you can visit it and work on-site which has to be more fun than doing it from just the book.
