I'll move this to communal discussion for you as it's really something for the community to help you with rather than the board admins/mods, which is what the help/feedback forum you originally posted this in is for. :)
Anyway, the easiest way by far is to use a blog system such as Wordpress (
http://www.wordpress.com) or Google's Blogger (
http://www.blogger.com/), which they host for you and all you have to do is log in and get posting. You'll be given a subdomain such as
http://brontox.wordpress.com/) and they provide a very easy-to-use system for adding pages and/or news posts. Go to either sites and you'll see example blogs (stands for "web log").
You might also want to try Google Pages (
http://pages.google.com), which allows you to create traditional websites where you edit each page by hand. Most who just want to post their thoughts and stuff don't really like doing this though as it requires a lot of finicky editing. There's also Frontpage and Dreamweaver for doing websites in this traditional manner.
