We apologize to those members who signed up since March 1st, but we have had some serious issues with a developer involved in the Microlinx project. Soon the Microlinx Bookmark Manager will be completely rewritten from scratch to eliminate many issues left by previous developers. Microlinx should be back online and better than ever within the next few months. We will retain our vision for the future of social micro bookmarking. Sorry for the inconvenience. & Thanks!
