http://puush.me/So, I've been "slightly" distracted by this other game lately, and I found out recently that most of the people who play it use the same filehosting service, which is made by the same person who developed the game.
And god, it's convenient.
Basically, you first need to register and download it. Then, the rest is easy.
It runs in the background of your computer, and you basically use the following shortcuts:
Ctrl + Shift + 2 takes a screenshot of you current window, and automatically uploads it to your personal online storage. It then gives you a link and you can share it right away.
Ctrl + Shift + 3 does the same thing but fullscreen.
Ctrl + Shift + 4 lets you specify an area.
Ctrl + Shift + U lets you puush files to your storage.
That's basically the gist of it. I can imagine this being really useful during PvP matches so that you don't need to do the stuff with prtscrn paste in paint upload to imgur/imageplay/image hosting site of choice.
