FWIW I have a number of forums from various vendors
My Swahili forum
www.waadventista.com (SMF) people asked me last nite to switch over to UBBthreads as people do not want to join it as it is, as they say it is too complex. AND they like the ubbthreads way better..
(NOW if they thing I am going to great a language file in swahili, it was tough enough the first time developing on for them... )
