Pretty cool!  More stuff for my Beginner Guide.

  RE xx:yyz 
1-  Is this hh:mmZ  the delta time *to* the next AOS?   Why the "z"?  Just an identifier?
2-  Is it rounded to the nearest minute, or is it the minute before AOS?

  RE +aa:bbc
3-  Is this duration in minutes:seconds?  If so, then what is "c" for?

  Would it be possible to have a place to send a message to that returns all the currently tracked sat names?   e.g send a message to "SatPass" and get a reply (or replies) with list(s) of sat names that will return pass info...or is the list too long? (I'm not familiar with this "TLE" thing)
