The main reasons why you should use a CMS

• you have more than 50 pages
• you want to display dynamic content
• you have multiple writers who create content
• your content is updated at least every week.
• you need a member zone
• you want to protect your content with password
• you want to display information from a database
• you want to make sure the design is consistent on every page
• the writers are non-technical (knowledge of html) persons
• you want to be independent from your web provider (no more need for a webmaster!)
