1. If it's freezing try holding the home and on/off buttons together until the apple logo appears, then let go and wait for the iPad to restart, if this doesn't help let us know.
2. There is no easy answer to this, a workaround is to put the words that you require in the contacts app, I haven't tried this myself but I understand that it does work. The dictionary does have some kind of learning ability, my dictionary for some unknown reason has learned the name of one of our most esteemed forum members, Twerppoet, I can't explain why but it has!
3. Can't help you with this one I'm afraid, you could try the User CP tab on our website, there may be some options in there.
