http://www.scenerydesign.org/2013/12/fsdeveloper-offline/FSDeveloper offlineAs you have maybe already noticed the FSDeveloper website is currently not accessible. The problem has nothing to do with the server, but for some administrative reasons the domain has been put on hold. We are working hard to reverse this and hope that the site is available again soon.If you want to keep up to date with the progress please check the FSDeveloper Facebook page, we’ll post regular updates there.Posted by arno at 8:57 pm on December 23rd, 2013.
