The quick answer to this question is 'yes' There are many web-hosts that already have Xoops pre-installed on your webspace, but as we have stated in another
FAQ, it's always wise to make sure you have the latest version installed and this is not always the case with some web hosts packages.
Also, the experience of installing Xoops is an important precursor for your own learning. If you really can't understand the installation guide, there is always opportunity for further explanation from the forums.
Some members will also help out on a more one-to-one basis if you really have problems.
Xoops is not a 'labour intensive' system, but you do have to consider a certain time requirement in order to setup your site and administer the content.
You don't have to be an experienced programmer to understand running Xoops websites
If you really want the 'hands off' approach, there are options for hiring web-builders and site managers from other sources.
