OK you're using italics for a ship's name, say Victory but you want to use the possessive. Is it Victory's or Victory's cos they both look wrong to me...
Z
Mind you they look more wrong in almost any font but this one where you can't see much difference in the 's'.
Oh, well done Emma, That's why I love this site, most of us would be writing away unaware of all these little things, but luckily there is always someone who can find the answer.
Wonder if anyone will ever ask a question that no one can answer - that would be a challenge.
