When you're on the IRC you need to highlight the proper person to get their attention. By typing in the user's name, it will play a sound on their computer or notify their IRC client and thereby getting their attention that way.
And, ah, Comodo is a tricky one. I did, however, find a way toggle the
Comodo Firewall on and off.
1) Right click on the system tray icon keeping the CIS interface in Compact View
2) Move the mouse cursor over 'Firewall'
3) Choose 'Enabled or Disabled' as per your choice
You can also turn off your
Microsoft Firewall as well but it may depend on your operating system. You might need to figure out what works for you.
1) Open Windows Firewall by clicking the Start button Picture of the Start button, clicking Control Panel, clicking Security, and then clicking Windows Firewall.
2) Click Turn Windows Firewall on or off. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
3) Click Off (not recommended), and then click OK.
