Hi Bolle, welcome to SimplyLightwave!
to answer your questions,
1) you yourself make the call if your a noobie or a normal user, you could say normal users have used lightwave for awhile or work professionally with it and noobie users are just that.. noobies (new to the program)
2) the prize is ofcourse the honor which is quite good itself, but you also recieve 5 points to download tutorials for
What 'under construction' thingy's are you refering to? :o
Happy waving! hope to see you in the challenge
