[TYPO3] last update and users

[Andrea Giorgini]

Hi list,

trying to get last_update from Peter Förger working I realized that I 
should specify the sysfolder containing my users. Is this ext working 
with BE users? If it is, I didn't find the way to add BE users to a 
sysFolder... if it is not, what's the alternative to show which BE users 
last modified a page?

thx

Andrea
