Use a chat technology that's so retro, it's cool.
IRC stands for Internet Relay Chat, and it's one of the oldest ways to talk to others on the Internet. It's also the primary way that people hang out and help each other in the Mozilla community.
Use the IRC Getting Started Guide to pick an IRC client and choose a nickname for yourself. When you're ready, join the newbies channel by typing /join #newbies. You can use this channel to ask for assistance from your peers and help them out, too.
Go ahead and say hello on this channel and see if anyone responds. If no one does, it's not because they don't like you–it's simply because they're all busy and none of them are currently looking at the chat channel.
If you can, find a peer and practice chatting with them a bit to become more comfortable with IRC and its commands. Once you're used to it, it can be an invaluable tool and a fun place to hang out.
