For some time I have wondered if this plugin works or not. Finally I have come to the conclusion that it works - but only with certain themes.
Unfortunately not that well with the ones I use, but whether or not it is the themes (which are becoming increasingly more complex) or the plugin (complexity squared?) - I really can' tell. I see many reports here originating from the same pond: not showing - text not fitted etc.
It became clear to me while doing a complex (well to me it is complex) little .div. thing to my presentation page. I was using the standard 2012 theme, where things worked, then moved it to my target theme (kippis) and the .rps. stopped working. Just a vertical slit.
I added .pre. - ./pre. tags around the shortcode and ye and behold - it appeared. Of course fonts are off and the text extends infinitely but it appeared. I tried using firebug to debug the situation, but I can't figure whats killing .rps.
