Gmail expanding?

I logged into my gmail today to find this peculiar form.

It seems that gmail have advanced to their largest yet, offering 50 invites per gmail account? Well strangely enough, I logged into my other two accounts and found they had 10 invites, and 5! It seems that this is either an error, or they are simply updating accounts strangely.

Want an invite, well i’ve got 50 so your welcome to them! Post a comment here if you want one.
