why is Jabber listed under 'home' on all my contacts?

Hi eloise47,

Thanks for posting your question about something you're seeing in Contacts on your Mac. I'm glad to answer.

What you're seeing is normal; Jabber is an instant messaging service, and if you click Edit on one of these contacts and click the Jabber drop-down, you should see other options. You don't need to enter any information or use those for your contacts, but it gives you the option to enter instant messaging or social media contact information.

I hope I've answered your question. Take care.
