Maybe this is of no help.
Or maybe this is what you need.
Rather than spend more time digging SQL and PHP I take the easy way out.
May cheap web space places offer a GUI called 'cpanel' and a feature bundle called "Fantastico".
Last count I have about three test sites. After I build them I run out of ideas. Poor motivation.I read a book on WordPress. The gist of it is that you don't want to do the programming, you just want to start up a Blog or a Chat or a Forum. Whatever. With Word Press, or one of the other ready made Blog in a Box things, you just install it the way it wants and POW you got a web site!
I could not get the WordPress to install by hand. So I used the Fantastico tool and presto. It worked right the first time!
Or, if you like the CH site, just install SMF. It's very easy!
To see this. just Google 'cpanel demo' and look it over. It uses mySQL.
