What do you mean by "test-out"?
Why do you want to get involved with other players? Assuming you're talking about blackjack, for most folks, it's a solitary pursuit. There's not often a need to take on other players; it just complicates your life, rarely adds value. Especially when you're just starting out and haven't had time to develop the skills to evaluate who you might become associated with. It's a tough world out there! Take it one step at a time. Realize that you're getting in a little late in the life cycle of blackjack, which is on life support.
