I Have two sites where I use Jomsocial, it work like charm in two langauges. It works very well. When there is a problem the support is available is very helpful. The support forum is very rich, we always have answers to our questions. I think only support it's worth to buy it, you'll not break the head. Very easy to install and configure. You can make a site only with Jomsocial and myBlog of azrul.
