Honestly its not that hard. Just read the sticky's, read a lot of posts and when you think you can contribute something to the discussion make sure you do. Its also not about find that one million dollar topic idear thats going to give you loads of merit. For me it was just about posting which I have been doing the last couple of weeks. Good luck on your journey.

To break it down:
1. Post to contribute
2. Dont go opening topics that are worthless
3. Read the rules
4. Try to post correct english
5. Have fun
