When search is not enough and you want to have your Mibbit client remember the channels you connect to you can setup details in your Account / Channels tabs and Mibbit will even auto-connect for you.
To do this log onto Mibbit and click “Channels” (signup free if you don’t have an account):
Next, add the entry(s) and save changes, simple as that. You need to know the network name (irc Server address) and the channel (usually begins with ‘#’). Separate more than one channel using a comma.
This is all assuming you identify your nickname manually, if you want it Mibbit can automatically identify on your behalf. To do this use the “Accounts” tab:
“Save changes” to finish. Now you’re all set. Each time you Log-In Mibbit will auto-identify and automatically connect to your channels.
