SRS, that's what I thought, too - but Dell wants $500 for 32 GB of RAM for my computer. Not what I consider inexpensive - I had expected to pay $100. There are different types of RAM cards, and different speeds.
MG, I haven't seen anyone tell people not to use "chat" when others are singing. What I'm strict about, is people who unmute and SPEAK when somebody else is singing. I think that is horribly rude. I can name you certain people who do it habitually, and I watch the mute button and stomp on them any time they try to interrupt a song.
Another think I need to learn - can I have a Zoom singaround and have it broadcast live on Facebook or YouTube for people who just want to watch and listen?
