Script Summary: prevents the "Welcome" bar from popping up on StackExchange sites (stackoverflow.com, serverfault, etc.)
Version: 1.1
Sets a cookie that prevents the "Welcome" bar from popping up.
Works on:
stackoverflow.com
*.stackexchange.com
serverfault.com
superuser.com
askubuntu.com
Update 1.1
It appeared that setting the cookie doesn't always work so now the script checks for the presence of unwelcome bar and physically removes it.
