This is addressed to the original poster and to anyone else who thinks there is something underhand going on.
If you really want to stop people arguing, as the title of this thread suggests, then stop fanning the flames by posting pointless nonsense. I don’t know where you get the information, which you post as if it were fact, but you are wrong on several accounts.
Firstly we, the moderators have not been given any orders by Transworld regarding images in signatures. We have never been given orders or instructions from Transworld on how to moderate this, their message board.
Secondly, Transworld are not using this forum to promote their books. This forum is for Pratchett fans to talk about their favourite author and his books. Transworld didn't have to create such a forum, but they did, which I think is really rather generous of them.
Thirdly, the links you refer to are for the http://www.terrypratchett.co.uk
homepage. This forum is merely linked from there. Transworld has been promoting this homepage for several years now, since it was created. Transworld are a publishing house, why shouldn't they create a homepage to publicise their books? I can see nothing wrong with that.
As I said at the start of this, if you want to stop the arguing, then stop posting about it.
I think everyone has had their say now - let's try and move on shall we?
