mathsteachers always were fairly dim i think tau could have done with your help or otherwise! however back to roneos it rhymes with bonios dimwit surely you knew that one! no really it 's the same as sellotape or even xerox think about it but not for too long please
i was going to tell you to look in the complete crossword companion for your lists ......i got mine for a couple of quid from one of the cheap bookshops.....but as you are so rude i don't think i will bother! lol!
why do you think that we are all dimwits may i ask?
some of us are not old enough to remember roneos....me included!
