Planetarium astronomy software.
In older versions of Asynx Planetarium it was sometimes a bit cumbersome to add personal selected cities to the list: First to search from a city list, then to type it manually into fields etc. After a while I thought there must be an easier way to do that and integrated an easy and efficient way to search from a HUGE database (with 4.5 Million cities) and then load it directly into the program. To prevent abuse and make sure your ID is unique I decided that the email is the login name. You can use webmail addresses, just make sure that your email gets to you and is not trapped in spam filters. If you don't like further emails, just uncheck the corresponding checkboxes. Of course your email will never be sold or given away, this project is financed by ad banners / donations and not by selling emails !
