Twitter commands no longer supported

I'm finding some Twitter commands are no longer supported.
FOLLOW ALL
LEAVE ALL

How do I do this now?

I like the idea of on a whim to "follow all" with Gtalk.
I can use "off" to stop it, kind of like standby, then "on" to start it again.
Or I can "leave all" to stop following in my IM.

Has "stats" replaced "followers"?

What happened to "get", how do I now IM Twitter for the latest post from all people I'm following (like a catch up).

Is "tracking" official - return a list of words I'm tracking...doesn't work for me?
and "untrack all" doesn't work for me either?

Also is there a command like tracking, but for users
eg. who of people I'm following am I gett ing in IM (eg. follow user)
ie. give me a list if users I'm following in IM delivery
Inappropriate?
