We have introduced social sharing feature over our website on the RTI forums. As our forums are highly popular segment, many people want to share the important and helpful post with their friends over social network. Earlier they used the 'email this' feature, but slowly it has lost the relevance as most of the friends are already on social network like Facebook, twitter etc.
With every post you shall see small Social icons as shown in the screenshot below:
That means you can find out what challenges your friends are facing and you can engage in ongoing dialog. Happy Networking and sharing.
