Firefox Chatzilla plug in

Firefox Users can download the Chatzilla Firefox plug-in and simply use the link to irc:// (This may work with other clients as well). You can add a bookmark to this URL, which makes reaching the page quick and easy, but you have to do it in a round-a-bout sort of way. Create a bookmark to any random page (such as this one), then go in and edit the bookmark. Change the URL to the one above, and edit the title and description however you want. Then clicking the bookmark will automatically launch Chatzilla and open the channel.

Getting an IRC client

Find an IRC client that seems appropriate for your platform (Win/Mac) and has the features you want. A web search for "free IRC client" should find plenty of options. Wikipedia also offers a comparison of IRC clients[1]. For Windows there is a free independent-build of X-Chat maintained as Y-Chat. Also, many messaging clients for AIM, MSN, etc., also offer IRC support.

Connecting to freenode

Here's the basic information that you'll need to tell your IRC client:

  • Protocol: IRC
  • Server:
  • Username: (choose something you like, see the section below for info on registering your nickname)
  • Password: (enter this if you've registered a nickname, otherwise leave it blank)
  • Advanced settings, which your client will probably set by default:

Port: 6667 Encodings: UTF-8

Joining #reprap

Use your client's command for joining a chat and specify #RepRap when prompted for the channel. If you are prompted for a password, leave it blank.
