So I am trying to share a public calendar and imbed it on a website but it displays the Skin of the user that owns the calendar. I see in the source code this debugging comment:

<!-- tz=timezone  date=YYYYMMDD   view=day|workWeek|week|month  notoolbar=1 folderIds=[...]
skin=skin-name color=defaultColor(0)|blue(1)|cyan(2)|green(3)|purple(4)|red(5)|yellow(6)|pink(7)|gray(8)|orange(9) -->
So it makes me believe that I can change the appearance and other settings but these variables in the URL doesn't seem to work. For instance

Doesn't seem to change anything. Any Ideas? I'm running 7.2.xx
