Automatic posting and reposting to Facebook and Twitter.
We have two 'pro' plugins. One works perfectly as advertised with nice feature options. The other being tweaked due to figuring out a subdomain issue. The support has been excellent.
The original Facebook plug was frankly pretty confusing (how to install), so I searched for a replacement. Found SharePress and had it up and running in minutes. Upgraded to Pro version so I can post to pages as well as default profile page.
Kudos development team!
I tested about 10 social publishing plugins but none worked as smooth as this one.
