One thing vendor's/participants should remember is that when your sound is on, you hear everything. I was in Ameet's booth for a few minutes with Jason and Ameet and had my mic on and all they could hear were my boys in the background so I graciously stepped away.
Later in the day, I was able to get back on and listened to people chewing and slurping drinks.
I found the individual chat's the easiest way to communicate my wants with the dealers and I had a few reach out to me after the show because they had located some cards that they thought I might be interested in.
Overall, I really like the virtual show and being able to talk/interact live with like minded people was a ton of fun.
