Welcome to the forums, subigo.
As for your question - Google will find your site if you have crawlable links to it.
You can also auto-submit you index page (only once required):
http://www.google.com/addurl.html
However, as I stated on another thread, Google does not like IPB. If you want forum indexing you need something like phpbb and vBulletin.
I tell you that even though you are a rival to my site:
http://www.comparative-religion.com/forum/index.php
Good luck with it.
