Hi!

So basically, I need the use of a CMS, to allow people to edit and add content to a website, but I don't want the whole website to be a cms...

So, can anyone suggest what would be the best (free) CMS to use, to integrate into a website so I can maybe let other users add news or events on a small part of the website.

Alternatively would it really be better to use something like Joomla! and have the whole website use a cms?

Thanks!

(p.s. massive cms newb)
