Good point, Chris -- to be honest I'm not sure whether you can do unusual spaced poems -- I feel it will do it's own thing - probably move left -- people write about poetry spacing -- but I always forget their suggestions -- but I've read nothing on this -- I cut and paste [using -- paste in plain text] - to keep the stanzas seperate or to not have spaces at all. In "Faded Years and Bygone Tears" I did a section that had three columns in Word, transferred it to Paint and then pasted it in as an image -- I suspect what you want cannot be done [I could be wrong] - Just in case, a link:
