G'day mates.
If you're wondering if you can use the chat hacks page, the answer is yes, but not if you abuse them. You must not use those tools for pretandance, whether it's avatar changing of someone else or changing your username title in the PM list. Those tools are mainly used for modifying the chat look and making some features more accessible. Users that will abuse those tools will be banend from chat.
Thanks for readin', and have fun.
