I have had many friends join BGA over the years, and none of them ever told me the lobby was confusing at all. But I really do think the new page is very confusing. Even regular members are struggling with joining and managing tables after hundreds of times using it.
My suggestion is for the page to look like this:

The top has all the info that's currently on this page without the top 4-5 inches of mostly empty space. I strongly believe that joining or quitting or managing a table is friendlier and easier to understand with these old features included.
I have a different suggestion as well. If new players are confused with the old lobby, perhaps the problem is the header at the top.
Maybe they are clicking on ''GAMES'' when they want to start or join a table. So this...

could be changed to this...

''LIBRARY'' makes sense as a place to look up games, and it doesn't sound like a place to go to play a game. Perhaps this is the only fix that was needed?
