It is with great regret that we will be closing our virtual doors in the upcoming months. With the constant changes with NWS servers, expensive programmers, authors unwilling to update, and a dwindling PC base with more and more users going mobile only, it has been difficult to maintain. We had hoped for a subscription but those of you who frequent this page replied with a resounding no, thank you. We got the message. Please be aware that a good portion of the software will continue to work, but many of you may want to look for alternatives.
