don't forget the fact that alot of the stuff being sold is nothing more than a copied template with a modified .css
Installing is pretty much nothing at all.
go to
http://www.wordpress.org & download wp 1.5 (2.0 has bugs)
go to your host admin & create a mysql database.
with your notepad or text editor, open config.php & see the lines for mysql user name, password & database name.. enter the info.
Now ftp the files.
in your browser, go to the domain the blog is on. You'll see a page that says install. click it, POOF!! you're done.
now login & blog.
I'll do it right now & be done in 10 minutes or less, & free...
