A bit about what I am trying to achieve. I am running an owners club for the Nissan Elgrand based in the UK. I current have a Facebook group, a phpbb forum, a media wiki, and an open cart shop.

The problem I am having is with the Facebook group. Facebook is so easy to use and integrate with that people can't break away from it. Also, the lack of integration between the various software I use is a pain in the ass. 

So, I am looking for an all in one software to cover all aspects of my site that also incorporates a social network that will help move people away from Facebook. 

So, I have installed the free version of oxwall available through softaculous. It looks great, but there are massive improvements needed to get what I want. I am overjoyed to see that the tools are available via the store. But, what I am not happy about is having to pay for all of said features before trying. 

I need to know that I am going to get what I want and in a use able format for my members before committing to spend nearly $600 (£450?). 

So, is there anywhere that I can "try before I buy"? Or is there a money back guarantee if the add ons I purchase don't do what I want them to?
