You have to be nominated by a current HOF member and then a vote is conducted by all of the HOF members. If you get 20 yes votes before 10 no votes you will be inducted.
Good question VD.. I was wondering the same thing. I thought that it had to do with the number of posts you've made or something like that. I've been on here for a few months and the information can be paralyzing sometimes. It takes awhile to sift through the weak posters to find the strong, consistent poster. I bet that HOF section is just jam packed full of winning picks!
