Seriously - every time I start thinking: What I really need now is product/feature 'x' FogCreek seems to announce it 2 days later.
Love Kiln, it's exactly what I was looking for. We're still on the startup edition - though I've purchased fogbugz with other organizations in the past - but now it'll be a whole lot easier to justify going to the hosted fee / user / month.
Hopefully this is the right kind of forum for positive feedback too. Great work!
