Filtered html ignores extra line breaks I'm using the Filtered HTML input format without a WYSIWYG editor. 

When editing text, if I put some text onto a new line by hitting return, when I save its fine.

However if I add another line (so there is a space between the 2 lines of text) by hitting return twice, when I save this extra line disappears. How can I stop this from happening? Thanks 

So I can do this:

But I can't do this:

Consider using the Markdown Filter. It not only solves your problem, but gives a more intuitive input option. 

If your users are used to using Markdown on StackOverflow, then they will love it ;)
In fact, StackOverflow was one of the first sites to integrate the Markdown format.
