[TYPO3-english] fe_user field modification

[Katja Lampela]

Hi,

I want to use existing field "title" of the fe_user table for other 
purposes and I want to change the type from textfield to textarea.

Now the installation is 6.1.9. Would someone be so kind to tell me which 
files I should modify?
