The newly refurbished VDR User Counter at
https://www.tvdr.de/counter.htm
now uses OpenStreetMap instead of Google Maps. If you have a user number and password, please log in at
https://www.tvdr.de/cgi/vdr-counter?action=edit
(click "Edit my entry") and check if your data is still up-to-date. If you don't remember your user number/password, enter your email address and click "Send me a new password".
If you're a VDR user and have not yet registered with the VDR User Counter, please go to
https://www.tvdr.de/cgi/vdr-counter?action=register
and join the VDR community.
Disclaimer: The VDR User Counter is an attempt to find out how many people are actually using VDR, so please register only if you are actually using VDR! Note that there is absolutely no obligation to register yourself in order to use VDR. VDR is free, open source software, so you can, of course, use it without anybody's approval. However, developing a program is more fun if the programmers know that it is being used by a great many people ;-).
Have fun! Klaus
