SocialStrap is a great tool for anyone looking to build a new social media website. The community of webmasters is strong, and there are a lot of great new addons, mods and guides that allow anyone to have great customization to their SocialStrap site. I have tried many different engines, and this one is the most comprehensive and the most supportive out there.

一款英文的SNS社交源码，包含小组 话题 等功能，支持多语言，看了一下，语言包不是很大，翻译起来还是很容易的。
压缩包包含2个收费插件和30+免费插件！有需要的可以看看。
