If you can get a moderator's attention I believe they have the power to change usernames. I could be wrong though, but wouldn't hurt to ask.
For starters I would definitely take a look at the tutorials, the links that mike5424 posted should be a good start. In general, I'd say you should just get familiar with the basics of DBPro -- Controlling cameras, adding 3D objects, checking for user input. Don't try to put everything altogether into a FPS yet, until you feel really comfortable with the language.
Since you seem to already have some experience programming you should be able to pick it up pretty quickly. Once you're familiar with DBPro and you're ready to start your actual game, you'll want to go through the following steps (more or less):
* Loading / Creating your 3D environment (whether it's a 3D object created in a level designing software, or a simple Matrix landscape)
* Adding user controls -- Mouse for looking, keyboard for moving and jumping
* Basic shooting and bullets (you'll need arrays for this)
* Some targets or enemies that your bullets can collide with and kill
I know it's kinda vague, but it's a start -- It's much better to try and conceptualize a project into achievable "chunks" rather than try to tackle something like an FPS game all at once. Again, for actual code implementation, your best bet is to just start looking at the tutorials scattered around the site and on the forums.
