[Typo3-dev] Using tt_address in a custom module?

[Simon Angling]

I'm thinking of attempting to write a yellow pages type directory for 
Typo3. Having never written an extension before I am in need of a little 
advice.

What would be the pro's and con's of using the already created 
tt_address extension to store the addresses in? In some respects it 
would seem this would be the best place to start but I am wondering if 
it would be better to start from scratch.

Any thoughts?

Cheers,
Simon
