How can they list games? Can you set an api endpoint to pull game list from and set a special encoding that w:a uses for game names. And what about hosting? There you should also set w:a exe and run it with special parameters. Which is that irc client that supports these? :O
OoO's WN script for mIRC can do that
you have to pay for mIRC, at least i think so, i paid for it once then never used it much, tomi offers great snooper for free
i guess it makes sense if you are a script nerd and like to hook these things up yourself and you consider it superior because you did, but i cant and id rather just download a program that does it for me with more practical features such as league searcher and wormnat2 support.
