Scarpozzi,
Make sure you put in your email address (or the email address of the miniteam you are cracking for). If you are cracking under your own email addy, then after you've dumped your first block, you should get an email from DNet in the next day or so. After that, you can be fully registered and join the team and also track your progress daily on DNet. Remember that joining a team doesn't happen automatically if you are not cracking for a miniteam, so if you are cracking as an individual, make sure and join Team AnandTech if you want your blocks to count for the team.
If you have decided to join a miniteam, let us know which and we will direct you to what address you should use for your proxy. If you've not joined a miniteam but are cracking on your own, then you should set your proxy address to proxy.teamanandtech.com ... doing so will enable you to see your own stats updated every 30 minutes throughout the day.
Whatever the case, it's cool that you're putting your machines to work.
Joe
