[TYPO3-dev] Wondering if my extension id is possible

[Patrick O'Hara]

First a little background about me.  I have worked professionally at a PHP
developer on and off for about 4 years.  My last gig was more that 4 years
ago however.  I have be working with Typo3 for about 6 years as a user.  I
have reviewed some of the documentation on how to write an extension and
obviously will be looking at it again.

I have a desire to filter email addresses in the output of Typo3 and make
them spam safe.  This is a piece of code that I put into my own PHP based
content management system that I used prior to finding Typo3.  My question
is a) is it possible for an extension to modify the output of Typo3 (that is
all the output), b) where do I hook in?

BTW, as I assume is obvious this will be my first attempt at programming
within Typo3.
