Hi Martha, you are almost there...
Weekend Chat is for everyone. It's a place to catch up on what people are up to and to share what you've been doing. New members can say hello, introduce themselves, ask questions, and meet each other. Our seasoned members can share progress or successes from their projects, give tips and advice, or chime in on hot topics.
So each weekend starting Friday morning check here on G2G to see the current weekend's Chat.
As David and Ros mentioned, This weekend's chat is at: https://www.wikitree.com/g2g/985418/welcome-weekend-chat-members-invited-february-14th-16th-2020
