Guild Wars 2

Okay this is bothering the hell out of me and i dont even know what to google to find the answer to lol but i was wondering what is that number in the menu at the bottom left corner its like GW2: 13,395 or some other random assortment of numbers.

It was in GW1 as well and i have no idea what it means lol is that like the server population? Or something else?

Thanks and sorry for the dumb question haha

bump come on lol someone must know!

Client version number.
