I'm not sure I really understand your question. If you'd like access to the freerolls and $5 buy ins you must meet the requirements, which can be found in those sub forums (I will provide a link in a moment)
For freerolls: http://www.cardschat.com/f31/cardsch...ements-145133/
Important notes: You must have 65 insightful and QUALITY posts and be a contributing member for at least 30 days. There is a temporary posting limit you can do per day in order to protect the site from spam. There is a LOT of content and discussion on this forum though, so it shouldn't be too hard to find spots to post quality contributions.
For buy in tourneys, I believe the requirements are 25 quality posts, but I'm not sure if there is a membership length requirement.
