If you are looking for a simple definition, Xoops is a highly dynamic web CMS (content management system) tool that is flexible, easy to use and object oriented. As an acronym, Xoops stands for Extended Object Oriented Portal System - which more or less tells you all about what it does as well.
Xoops is a tool that is meant to assist anyone from the novice to the veteran to build a workable website perfectly tailor made to their needs. With Xoops you can easily build a simple personal blog or an intricate interactive community website with equal ease - even if you do not have much expertise in or about the use of computer or the language needed for this purpose.
While building a personal blog might sound (and be) easy, the same cannot be said about a large business or community website. With interactive websites the system needs to be scalable so the members can view whatever they want, whenever they want and support such interactive systems as mass mailing (to members), exhibition of profile of each member, unlimited signing up of memberships, etc. With Xoops you will never run out of themes (the name given to different styles of web pages) that you could modify, tweak and adopt to make your own website unique and most manageable.
There are many other features that Xoops offers the webmasters which can often mean the different between success and failure of their online existence. Some exceptional features that you could use are shopping cart known as ZenCart or osCommerce, you could have online chatting, customer polls, provide RSS feeds and the like which would make your website most professional both in looks and in functionality.
Xoops is easy to install and set up just as it is to administer. When you use Xoops you were, are and will stay in charge of all that goes on with your website. You would even be offered the WYSIWYG editor to use so you could customize the content in the easiest possible way.
