Just give them time. I had to beg the dev team to give me an invite code. I am working on some "features". You can add custom fields to track. Forum name, etc. What ever you can think of.
Update: I talked with the dev team, and they assure me that there will be no codes given out until next week. They are upgrading their server farm. Coupled with a software update, they assure me that next week it will be open and everyone will be approved.
