Sifter isn't quite finished yet. We're targeting a public release sometime around the middle of 2008, but it could take a bit longer.
Sifter is designed to be a bug and issue tracker for designers and non-technical people. However, we're pretty optimistic that technical people will like it too.
Sifter is created by the folks at Next Update. We've put together some blog posts about our design decisions that can explain what Sifter is all about, and we have answers to some frequently asked questions that might, you know, answer some of your questions.
If it sounds like Sifter is something you might be interested in, you can stay up to date with our progress by subscribing to the Next Update blog feed where we're sharing monthly status updates.
However, if you just want a heads up once we're open for business we have an email announcement list for just that purpose. We're also twittering if you're into that sort of thing.
