if no one plays WWP, how come the old Team17 forum thread (WWP color fix) has got 600000+ views between 2008 and 2013, more than 70000 downloads, people registering solely because of the fix, and tons of comments? Also look at the view counter of this thread, for the record, and notice how guests come here within 5-10 minute periods.
Another cause of the WWP server inactivity could be the broken IP address of the WormNET server (no one can connect to the server without modifying the game or redownloading the patch again, because Team17 changed their IP address various times in the past) and the crash issues that cause incompatibility with the newer systems.
