Is it possible to create multiple websites within a single joomla installation and is there a built in blogging feature?

Hi Dennisfoy,

Are you starting a website from scratch or currently working on an existing one with a created template already?

Here is a template that comes with a portfolio feature:
www.joomlart.com/demo/#joomla25-template...=web&utm_source=blog

Here is a portfolio zen extension which is widely used:
extensions.joomla.org/extensions/directo...tion/portfolio/10532

There is Easy Portfolio, but doesn't have any reviews on it, but looks interesting to check out:
extensions.joomla.org/extensions/directo...tion/portfolio/21333

Are these similar to what you are looking for?
