1. GMs have personal emails and PMs. If you're serious about being a GM, you would message them privately. If you're played Dr then you know how the community reacts when they find out a certain person/player is a GM. Say you're applying for a job at Microsoft. Would you go in front of their headquarters with a card board sign saying "Hire Me"?
2. Spell check. Grammar mistakes is ok since English is not your friend language but it takes less than 5 minutes to run your post through a English spellchecker. Not doing so seems unprofessional, lazy, and like you're not serious.
3. There's a suggestions forum, if you want to add more features for the same, you can suggest it there.
4. You don't need to be a GM to make a difference. Kamos has made numerous fixes and contributions without an official GM title. By going "I want to be a GM when I have nothing to back me up" is the same as saying "I want to be an attention whore and have all the power and authority to abuse it.
EDIT: you say lots of sections aren't finished yet on the website? why can't you code that up without being a GM? PHP and HTML integrate together. You can code or write up the information in HTML then send it to the GMs to use. There's a different between wanting the POWERS of being a GM and just wanting to make the game better.
