A lot of people out there have met their significant others through the computers and why shouldn't you?
There's just a few things to follow and to keep an eye on.
When in IRC chats there's the "/me" command to do your actions.
Just type it in like this: /me your action here, and it will print out your name and the action you just did.
Try not to yell, this is where you either type in all capitals or use text editing to increase the font size and bold type of your message.
