Its easy Mike, you have to be obsessed with writing 4 paragraph replies, never have a strong opinion on anything that may slightly offend anyone.
Be way too serious/enthusiastic about what is essentialy a bit of a laugh.
Never say anything that might make you look bad and generaly be realy " positive " about stuff even when you dont want to be.
Oh, also you have to be nothing like you are in real life and be really worried about what people may think about you.
Discovering normal mountainbikes might give you points now too.
