Hey,
I've been using this screenshot tool for ages and It's a really nice tool to quickly share something,
It's called ScreenSnapr, you may already know about it but I thought it'd be cool to share to you guys :)
Simple, Download, Install, Run, Press CTRL+1 (Or your own set binding) and just drag an area of your desktop, simple, then it automatically uploads it and puts the link on your clipboard, then just paste it and send to whoever :)
Here's my desktop captured with Snapr
Just thought i'd share.
xpression.
