I just opened the .fla (with Flash MX) file and scaled the "pin" library item down. (ctrl-L openers library items). Then "publish" it.
What I'd really like is to remove the usernames, so they only show up with a mouse over... but have NO clue how to do it.
Here's the map with 131 users in the USA map. I'd guess by the end of the week there will be as many as 500, obviously all major metropolitan areas are going to be bad. Dallas for example is already messed-up.
