Thanks for the warm reception. Simon, I just have to say "wow". Even if it's unfinished, you've still accomplished a lot. I am a Java programmer myself, but UBB is written in PERL which allows for lots of quick and dirty modifications. Unfortunately, that also means that the code starts getting unreadable after a while.
It's a blast running witnet. I get a lot of personal satisfaction from providing a "safe" place for real witnesses to discuss important issues.
