It seems like it would be more effort to patch the old tracker software, so a new one is being made. Hopefully this one will be less exploitable!
We're holding a contest for the design of the new tracker. This is a page a lot of people see, so please do a good job with it. Details here.
Just to reaffirm things, I don't believe the old tracker was shooting viruses and stuff into people's computers. If it were really that bad, we'd have a lot more of an issue. It just seems like someone somehow got in and added a harmless spam redirect.
We'll probably hold off on releasing more Agito for now. If the tracker is still down when our Go-Busters is ready for release, we'll just do a direct download release.
