When I first started working on the rebuild for the official Rob Zombie website, one of the things I was asked to do was find a way to build a community on the site, so fans had a place to go, share and hang out, as well as get all the latest news on Rob Zombie.
After much hunting, and trials and errors with other plugins, which weren't always theme compatible, too complicated, or load bearing on the site, I came across WPS.
What more could you want other than everything it delivers - a forum, a profile, do as you wish groups, and so much more. I love this plugin! And the fans do too! They have a home, a little space on the site that is their own and I can not praise the work of Simon enough.
Whether it is the delivery of the product, the transparency of development or the faultless one-on-one help if a problem should arise - you can not go wrong.
As the web designer and web manager for Rob Zombie, all I can say is - go use this.
