* Friendica is a communications platform for integrated social communications
* utilising decentralised communications and linkage to several indie social
* projects - as well as popular mainstream providers.
*
* Our mission is to free our friends and families from the clutches of
* data-harvesting corporations, and pave the way to a future where social
* communications are free and open and flow between alternate providers as
* easily as email does today.
