[TYPO3-shop] fe_users and tt_products

[Torin Finnemann Jensen]

Hi

Im working on a site with a shop, a forum and a few user features. For 
the forum I've managed to set up registration and login using the 
fe_users table (newloginbox).

When buying, using the shop (tt_products), I would like registered users 
to be able to log in and get the form fileds (adress etc etc) auto 
filled. Does tt_products in some way support interaction with fe_users? 
Is there some sort of guide or instruction on the net somewhere or could 
anyone point me in the right direction?

I'm aware there is a tutorial and some examples. One of the examples is 
"EMAIL_NEWUSER_TEMPLATE", for mails being send to new users registered 
during buying, so I imagine there is some sort of support. I just 
haven't been able te see how to set it all up.

Regards
Torin, still rather new to typo3
