I tried many ticker and scrolling news plugins. This is simply the best of them. It's simple, customizable, and rich-featured. Also I managed to make it work in a single site for both RTL and LTR with a bit of css code added to to the style.css and rtl.css of the theme. Also don't forget that it's totally free, while some of the plugins I met were very poor while the PRO version doesn't seem to come near this. Thanks for the author.
