Hey there!
Participating actively in the chat, for sure enhances your overall experience in this forum. Also engaging with other players offers you a opportunity to share tips, strategies and insights. So, I'd say it's quite effective to participate in the chat if you're aiming to have a positive impact, to be better informed and to know how the games of chance work.
Also, I must ask, what do you mean by weekly competitions? We have free weekly tournaments, you can check it here, and you can get free spins and the winnings are dependent on your luck. By playing, you collect points for winnings with the free spins and the Top Players get Prizes.
