The dictionary feature is not useful for me either. That book Harry quoted was good because I didn't know those words, but , also , they are not words I see in anything else I read , so it's not normal usa book!
ha-ha and quintain are not stuff I would read, yeah if I was reading chaucer and shakespear and lots of old time guys , yeah , I would need a dictionary, but , I don't. I read stuff that is NORMAL !
You guys know what I mean.
p.s. but it's useful to have dictionary and to the first poster, enjoy your 600!
