We use Simple:Press forum on a site for owners and or drivers of Citroën, Peugeot or Fiat vans. Like the Berlingo, Partner, Fiorino, Jumpy, Scudo, etc… The vans from the PSA citroen peugeot group so to speak.
The site is completely in Dutch because we focus on the Netherlands en Belgium. Although we have a German member. 
Small at the moment, but hopes for the future!
You can find us at the PSA-bestelclub

Thanks!
Well I for one think Simple:Press works a lot easier and better than phpbb. The forum software that was first used.
When I became an admin I could persuade them to make the switch to WordPress and Simple:Press. And now the first adminstrator (still admin by the way) is truly won over by this combination. 
Great new. Thanks for the glowing endorsement.
And good luck with the future of your site.
