[Orgmode] Changing paragraph setting in Latex export

[Paul Mead]

Hi

I'm trying to export an org-mode file to Latex but I've got a couple of
niggles with the output.

Firstly, there are no spaces between paragraph breaks, so my text looks
horribly bunched up (I'm converting to RTF using latex2rtf, btw)

Secondly, the paragraphs all come out fully justified - this looks
pretty terrible on a fairly wide page (A4 with 1" margins in my case),
and I can't seem to find a way of changing this layout from the org
file.

Can anyone help with this please?

Thanks
Paul
