I seem to have dropped something.....

you could have left 1 for someone else but still, my pleasure

You took all of them for yourself? Nice...

No need to. ;) Thanks for the drop anyway.

(but people who are lucky enough to grab keys should let it be known in the thread because, you know... Manners.)

You could post used keys, so the ninjas couldn't get them.
Then the first ones to post "All used, but thanks anyway" get the real keys on steam chat. :)
