If you use other extensions by RSJoomla! (like RSMembership! or RSForm!Pro) it integrates perfectly with these to get even more functionality.
And last but not least: the support is amazing and answering in less than 24 hours!
If you purchase the MI version your possibilities are unlimited as you can add each connection or adapter multiple time. This allows for example to paste on several Facebook pages, to sent changes out per e-mail immediately while using the queue for social media, to use a different text for new vs. edited content...
When I first downloaded the extension it had several trivial errors. The support however revealed itself to be reliable and very cooperative. Everything - even minor customizations - was solved within a week. They even logged into my website to check configuration and help with problems.
Although it is an expensive extension, it is worth its money as it is by far the best social auto submit extension I know!
And if you are not done, then the support is answering in less than 1 day to your support requests and even helps by checking your configuration or logging into your site to find a solution. Even small fixes are released in less than 1 day. The perfect mix for a commercial extension.
