It's easy to get started here on this website. Knowing some of the basics will help.
What is a Content Management System?
A content management system is software that allows you to create and manage webpages easily by separating the creation of your content from the mechanics required to present it on the web.
In this site, the content is stored in a database. The look and feel are created by a template. Joomla! brings together the template and your content to create web pages.
To login and to be able to create and edit articles and even delete your own, you have to register first to make this possible. When registered, an email will be send to your given email adres with a confirmation or activation link. After this step you are able to post on this forum. You can also post as guest but this will be screened first. So make it simple for yourself and register, its much easier.... and for me to keep track who and what!
Creating an article / reply or edit
Once you are logged-in, a new menu will be visible. To create a new article, click on the "Submit Article" link on that menu.
The new article interface gives you a lot of options, but all you need to do is add a title and put something in the content area. To make it easy to find, set the state to published.
To close things for now
There is (going to be) a lot to see here, but I find it also boring at times, so don't forget to have fun and play some games on your computer.....
