Well, since I couldn’t fix a particular bug myself and the other developers think all is working well with Yahoo under KDE’s Kopete software, I had to switch over to the second best way to connect to IM networks – BitlBee via Konversation. This post is merely a note to self for adding Jabber accounts for GMail and Google Apps Mail accounts in BitlBee, once setup.
To add GMail is easy, using the Jabber protocol:
account add jabber username@gmail.com password
To add Google Apps Mail needs one more step:
account add jabber username@domain.tld password account set 0/server talk.google.com # You may want to replace '0' with your account number via 'account list'
account on and have fun with your now-more-powerful IRC Client.
