 ## Current Status
 The current version of the program should be considered a beta release. The program works well, but there will most probably be bugs and possibly sub-optimal performance in some scenarios. On the other hand, this is the ideal time to have an influence on the direction of the development of Nomad Network. To do so, join the discussion, report bugs and request features here on the GitHub project.

+## Development Roadmap
+
+- New major features
+    - Network-wide propagated bulletins and discussion threads
+    - Collaborative maps and geospatial information sharing
+    - Facilitation of trade and barter
+- Minor improvements and fixes
+    - Link status (RSSI and SNR) in conversation or conv list
+    - Ctrl-M shorcut for jumping to menu
+    - Share node with other users / send node info to user
+    - Fix internal editor failing on some OSes with no "editor" alias
+    - Possibly add a required-width header
+    - Improve browser handling of remote link close
+    - Better navigation handling when requests fail (also because of closed links)
+    - Retry failed messages mechanism
+    - Re-arrange buttons to be more consistent
+    - Input field for pages
+    - Post mechanism
+    - Term compatibility notice in readme
+    - Selected icon in conversation list
+    - Possibly a Search Local Nodes function
+    - Possibly add via entry in node info box, next to distance
+
 ## Caveat Emptor
 Nomad Network is beta software, and should be considered as such. While it has been built with cryptography best-practices very foremost in mind, it _has not_ been externally security audited, and there could very well be privacy-breaking bugs. If you want to help out, or help sponsor an audit, please do get in touch.

 It might be nice to keep that handy when you are not connected to the Internet, as it is full of information and examples that are also very relevant to Nomad Network.

 If you have Internet access, and just want to get started experimenting, you are welcome to join the Unsigned.io RNS Testnet. The testnet is just that, an informal network for testing and experimenting. It will be up most of the time, and anyone can join, but it also means that there's no guarantees for service availability.
 
 The Testnet also runs the latest version of Reticulum, often even a short while before it is publicly released, which means strange behaviour might occur. If none of that scares you, add the following interface to your Reticulum configuration file to join:
 
 >>
-[[RNS Testnet Frankfurt]]
+[[RNS Testnet Zurich]]
   type = TCPClientInterface
   interface_enabled = yes
   outgoing = True
-  target_host = frankfurt.rns.unsigned.io

+  target_host = zurich.connect.reticulum.network
+  target_port = 4242

 If you connect to the testnet, you can leave nomadnet running for a while and wait for it to receive announces from other nodes on the network that host pages or services, or you can try connecting directly to some nodes listed here:
