2. THE NEW mIRC/XFire
The community has abandoned mIRC and completely switched to Discord https://discordapp.com/ for arranging matches and freelancing/smurfing. You also have the option to use it for voice comms during matches. Discord is basically Teamspeak and mIRC rolled into one, and is way better in both cases. Please create an account and click on the following link https://discord.gg/4VDqDdp to join the MoHAA channel, once you have joined it, you will always be in it, you do not have to click it everytime. Click on the wars text channel if you are not already in it. Most people have already migrated to Discord, and you probably won't be able to find a war without it. You can use it in the web browser, or download the desktop app.
