I'm very much looking forward to Edge being released, but am okay with the delays as I know what DCS are going through. I have been developing private cloud File Sync & Share software for about 3.5 years now, and I am often promised date by my developers we're entering just entering beta any day now (when I can find some beta testers). I looked at an old schedule on the wall and the estimated completion date was 14 months ago and the previous release date was before my 22 month son was even born! Developing any software takes much longer than expected and cost much more too. Go easy on DCS I'm sure they're doing their best and they have a huge amount of pressure on them already.
