[themes] overriding function in template.php

[Matt Funk]

Hi,

i sent out an email with a question related to overriding functions in 
template.php a couple of days ago. Maybe i was unclear or so, but no one ever 
responded. However, i am not the only one who got a little confused. 
So maybe, if any of the experts could post a response to the issue at:

i would greatly appreciate it.
Also, is it possible to 'subscribe' to an issue? I.e. is it possible to get 
notified when someone post a reply?

thanks
mat
