Code::Umbra has been an interesting project and since its creation, it managed to attract thousands of users, with a steady flow of about 2k visits per month. However, the site has been abandoned by authors, with no activity in the last 2 years.
I have decided to take the site down. The domain is paid for in advance, but once it expires, I have no intention to keep investing in both the domain and the server. This site will therefore soon be gone forever.
