Category integration

Hi, I have a question about categories. Is there a way to use the existing categories in my joomla site with Easyblog? I'm using MarsEdit and it does not pick up the Easyblog categories, just the original ones set up prior to installation of Easyblog. The site is just being set up but I want to make sure that the categories are correct and accessible before going any further. site address: http://www.squaretechosts.co.uk.

Thanks,

Clive
