[TYPO3-mvc] Extending an existing model and adding fields

[Zoran Zaric]

Hello everyone,

I'm going to extend Tx_Extbase_Domain_Model_FrontendUser. Basically what 
the blog example does with it's administrator.  I'd like to add some 
fields though and am not sure how to do so.

Any hints?

Thanks and happy holidays!
