Gotdotnet Workspaces appear to be a sort of Sourceforge for .NET. I just found a post about Retina.NET so I thought I'd check it out.
Unfortunately, there's no real detail on the homepage, there's not quick FAQ or About section, and the fucking documentation section asks you to login!
Great stuff chaps. I'm sure your product is very clever, but if it's this hard to find out about and you're that poor at presenting it, I'm not interested.
