I have had the same problem - the Audiogon listing engine wouldn't recognize normal carriage returns in the INITIAL placement of my ad. I tried a few times - even inserting the HTML tags for "br" and "p" to force a return and neither one of those would work either.
The only way to make the ad readable was to first list the item incoherently - and then later, in the EDIT mode, correct the problems.
