Well, I spent 16 attempts trying to register - still do not know how I could get through
1. change picture mechanism is not working - kicking you back to the rules reading page or says "you are not allowed bla-bla-bla"
2. audio version malfunction for Mac
3. the letters are really unreadable and no info if they should be typed capital or not - I guess capital because the set of attempts with capital was successful )
