Paragraphs (or lack of)

Nps

Any ideas as to why I can't use paragraphs in my posts on the new site? (New paragraph?) No matter how neatly I format my posts, when posted, they are just one big block of text. (New paragraph?) I've given up answering queries with calculations in, as a big block of numbers would be just too confusing for the reader. I'm using an ipad by the way. I suppose I should check what my posts look like when I use the computer but I rarely use it.
