TechKnow has failed to get a sponsor for a long time, resulting in no new Android projects, rom development or anything. This resulted in a huge drop of visitors and forum activity. The new projects I'm working on aren't very popular, feedback is nearly nothing, some topics get 1000's of hits without a single reply. The host of TechKnow stops near the end of the year, and moving a dead forum would cost time and money.
This is the end. Enjoy the last months of TechKnow.
