I needed to create some documentation with screen shots.  All of my co-workers use SnagIt and I have used it in the past, but I was curious if I could find an alternative.  My searching found Greenshot, a free and open source screen capture tool.

The user interface isn't quite as polished as SnagIt, but it does everything I've ever used the tool for: Highlighting, Text Boxes and Arrows.

Greenshot appears to have recent activity.  The last blog post was December 2010 and in the forums the developer said they were working on version .9 in January 2011.

I'm currently using SnagIt version 7.2.5, the latest paid version I own which sometimes refuses to take screenshots since I upgraded to 2 monitors.  If I continue to have issues I think I will stick with Greenshot instead of paying for an upgrade.  Anyone know of any other alternatives to SnagIt or Greenshot?
