GROU.PS is a social applications platform that gives you all the tools you need to keep your online community connected.

More formally, we call our product a social groupware – some also call it DIY social network, or white label social network. But technically speaking, we prefer the term social operating system to describe what we do here.

GROU.PS gives you a bunch of modules that you choose from and mash up very easily! You can enrich your site with blocks too; blocks allow you to copy/paste 3rd party widgets into your site.
