Ability to find users using a 'freinds' list

[NujumKey]

It's a simople freinds list idea i had. I'm always using forge mods in my vanilla minecraft and so are a couple of my freinds. If minecraft forge implemented a 'freinds list' (preferrably saved to your computer so it doesnt change during force updates) or a way to see if your freinds are online we'd be able to know when one of us is playing. It would make it easier to  find other users, especially if there was a way to find out the server they were on, unless they didnt want to show it in which case there should be a disable options.

Won't be implemented in forge, make a mod for that.
