I found Screenr a month or two ago and since then have fallen more and more in love with it.
Screenr allows you to record short videos of your screen, with accompanying audio, and post directly to an online sharing site. You get up to five minutes per recording, and seemingly there are no limits. It is BRILLIANT for reporting bugs with tools, recording short tutorials, and the quality, for a free tool, is wonderful. I just hope it stays free.
The main advantage for me is the instant sharing ability. With other screen recorders there are cumbersome processes to go through to share in this way – this is instantly available and that has made a big difference to my day to day here.
I recorded a short video here using Screenr for you to see what I mean.
