change me to my name in chat

Hi Linda! This is a little misleading for a lot of folks 😉 
The other attendees actually see your name as you entered it; YOU see "Me" in Chat so that it's easier to pick out your own name when scrolling through the conversation. (In other words, every attendee sees "Me" when viewing their own messages in the Chat panel.)

You don't need to change anything - you're all good!
