are you finished with the test site? And are you hosting the site from home? If so, it's do-able but for a couple bucks a month (normally they give a bigger discount if you pay for a full year) you can get some cheap online hosting but expect cheap service.
well, our previous host is offering an excellent deal at the moment but it requires an advance payment of the next 2 years. They provide a free domain every year though (they might charge for privacy guard though). And if you're gonna be doing WordPress, I dunno how good it will be. But I'm sure you remember our hiccups we used to get back when we were on the SMF forum.
