tyking,
First off, forum rules require you to post your name. Nobody gets away here with a mask on!
Best way to do this is click on "My Controls" and then "Edit Signature". Put your first and last name in the Signature box along with what ever else you want (fav saying, personal web page or whatever) and click "Update my signature".
Second, I do not know how old you are or how much experience you have in modeling but from your questions you sound like your just getting started.
Best bet is to simply build the models you have as cleanly as you can and spend some time reading old posts on this forum.
There are TONS of information here if you'll just take the time to check out some of the old threads.
