For a quick down & dirty answer. If you are using the text editor that is accessed via the
Add Topic, Add Reply buttons or the

To always get a single blank line between paragraphs do the following in the text area of the editor...
This is the first paragraph test This is the first paragraph test This is the first paragraph test This is the first paragraph test This is the first paragraph test This is the first paragraph test.
This is the second paragraph test This is the second paragraph test This is the second paragraph test This is the second paragraph test This is the second paragraph test This is the second paragraph test This is the second paragraph test.
This is the third paragraph test This is the third paragraph test This is the third paragraph test This is the third paragraph test This is the third paragraph test.
(Note: the asterisks in the above tags must be removed, they are put there to prevent the code from being executed.)
Then regardless of what it looks like in the preview window, it will come out like the following when you click the submit button and post the reply. Additionally, if you go back and edit your reply you can use the line-break tag as your indicator as to where one paragraph ends and the next begins...the other advantage of this format is you won't loose the spacing if you go back and edit your reply.

Just as an indicator so that you can see that I've edited and re-posted this reply I've included the following smiley which gets whacked each time I re-post (i.e. indicated by the addition of the " border=0>).

" border=0>" border=0>" border=0>" border=0>" border=0>" border=0>
