As I've only just now installed this plugin for the first time and have only used it once so far, this review won't be a thorough one. That said, I am absolutely thrilled with this plugin! It's a huge time-saver and limits the need to have to make multiple posts of the same "news" item to all one's social network groups.
Setup was easy - though Facebook tries its best to make it a pain, but can't blame the plugin author for that! - and I love being able to choose which page to post to.
I just wish it would automatically go to all other social network type of feeds as well (Twitter, et al). Then again, maybe it does and I haven't figured out the hows of that yet. I did notice some other options in the settings. I'll have to fiddle and see.
Nevertheless, this is a very cool plugin, and I recommend it.
