Im new here and I've read this bitcointalk in a site and I'm interested cause I really like and open forum or a thread that they said. I observed most of their topic are most interesting that have a content sharing ideas and have an empower of helping others who did not know like us me. Can someone help me or give an idea  cause I wonder in their profile that there's have a Rank, Activity, and Merit .

Hope someone can notify me in, my concern as a newbie. Thanks in advanced.
