Shows you how many gmails you have.
**Small update: Google change the URL it uses **
This requires SysStats 2.5.2, which you can get on this site. You should also install MSXML4, if you haven't already. You can get it here:

After you've installed SysStats and MSXML4, unzip this into your docklets directory, add a SysStats docklet to your dock, right click on it and load gmail.ini.
You will have to configure the docklet for your gmail account: Right click on it, select configure, hit the 'meters' tab, select the GMail meter and hit configure. Enter your username and password.
