I am now using Telegram for official support / notifications about server issues. You can find me here: https://web.telegram.org/#/im?p=@PanamaCityPC
If you wish to be notified of server events, please send me a message indicating you're coming to me through/about Simutrans.
Telegram is primarily based around mobile phone numbers, although any phone number will work; I don't think I need your mobile number to add you to a broadcast group, but I may be wrong; I'll edit this if it turns out I do.
Note that Telegram runs on Windows, Mac OS, Linux, Android, iOS, and Windows Phone, as well as a client for browsers (the link above goes to the web browser). If you sign up, it uses your phone number as your authentication. It will try to text you with a verification code, and if you don't get that code in a couple of minutes, it will attempt to call and give it to you by voice (so you can use a non-cellphone number). It's a neat service - very quick. If you want more information, check out http://telegram.org/
