If you want to setup a phpBB forum like this one at a low cost, you can do so at
www.VizaWeb.com (with a "z", not a "s"). They pretty much do everything for you in terms of hosting and setting up the MySQL database and configuring it to work with phpBB. Notice that their starter package at $2.95 a month includes one-click phpBB2 setup. If you have ever tried to set up phpBB/MySQL on your own you will greatly appreciate how they have dramatically simplified the process. They also include Fantastico and cPanel which provides a wide variety of web hosting features that are available with a few clicks of the mouse. I do not know how they manage to do what they do for such a low price. We have been using them for several months without problems.
