@sundogplanets It looks like the instructions for joining are in the readme on the github page for their source code.
Station ID
If you want to join our network of global cameras, please send me an e-mail and I will give you a station code. The codes are made up of the 2-letter ISO code of your country (e.g. DE for Germany), followed by a 4 character alphanumeric code starting at 0001 and ending with ZZZZ, giving a total number of 1.5 million unique combinations for every country. For testing purposes you might use XX0001.
