As there is no advantage to the newspapers of having posted entries (financial advantage), I wish that we were able to send in by email.
The post down here (Cornwall) can be unreliable and I often think that I should be putting on a 1st class stamp to try to make sure that it gets there on time.
Failing that, I also wish that the papers would make all their crosswords have longer send in by dates, like the You one. I can see no real reason why the dates cannot be longer, it's just a case of printing answers one week later!
The People I have given up on as that has to be in on Wednesday, though I can see why with that one as they want you to phone or text an answer - they make money by it.
