In either postbit or postbit_legacy template find this:

		<!-- message -->
		<div id="post_message_$post[postid]">$post[message]</div>
		<!-- / message -->

And replace it with:

		<!-- message -->
		<div id="post_message_$post[postid]" class="msg">$post[message]</div>
		<!-- / message -->

Then in Main CSS at the bottom "Additional CSS Definitions add:

.msg {
  font-size:13px;
  line-height:13px;
  letter-spacing:5px;
  word-spacing:11px;
  }

letter-spacing = spacing between characters
word-spacing = spacing between words
line-height = spacing between rows

Change the values to suit your needs. I used "px" but you can use "em" as well.
