Here are some areas you may want to check out to get your site started. The RV Site builder is a template based web site builder which allows you to build a web site fast and easy. There are close to 700 templates to choose from and we have a knowledge base area regarding that web template builder:

The RV site builder is not sophisticated but it will allow you to get your site live quickly. If you are good at following directions and tinkering with things we would suggest you look into 2 other free web site builders that do allow you to build more sophisticated web sites. Those are Joomla and Drupal. You can find information about both of those systems at their respective web sites:
JOOMLA.ORG
http://www.joomla.org/

DRUPAL.ORG
http://drupal.org/

Both of those systems have extensive knowledge base sections as well as community forums which are very helpful.

To install either Joomla or Drupal you can reference our knowledge base articles at:

DRUPAL INSTALLATION

Both Joomla and Drupal are part of your web hosting service package you purchase here at Green Geeks. A last option which is more sophisticated than the RV site builder but less so than Joomla and Drupal is Wordpress. Wordpress is a very easy to use blogging software that also allows you to build a web site. You can learn more about wordpress and their community at:

Also here is where you would go in our knowledge base to learn how to install Wordpress for your web site:
