i have the program and i like it very much..this programs uses much less server resources compared to other ASp alternative .. even with chat logging enabled its processor consumption is quite low..loads in many browsers without a problem..the chatroom also consumes much less bandwidths.. the only thing which travells between the server and clients are characters so u can count the characters to find out how many bytes / bits r consumed 
and u need to simply edit one file to make the chat work with a user databse of WWG..tho this process is painsome..especially when dealing with the encryption of WWG
