Not 100% Tested, but this basically stalks the log files of the Minecraft INDEV server. Just pop it into your remotes and then type /checkf #Channel Once and it will start up automatically when you connect from there onwards. If it doesnt pop up with a dialog asking your minecraft folder on load then type /set %mi.fol PATH/TO/FOLDER

What the /checkf will do is tell you when a user connects or disconnects and when they message on the server it will also message the channel.

Some other commands:

!players - Current online players
!admins - Lists the admins
!url - Url of server

I will add more and more over the next few days for my server then add on to here. Thanks :D

(Partially tested meaning I added a few things while adding it to hawkee for usability)

alias mf return %mi.fol

on *:LOAD:{
set %mi.fol $$?="What is your minecraft server folder path?"
}
alias f { 
  return $mf $+ \ $+ $1-
}
alias prop {
  return $remove($read($f(server.properties),w,$+($1,=*)),$+($1,=)) 
}
alias checkf {
if (!%mi.chan) { set %mi.chan $1 } 
  if (!%mi.l) { set %mi.l $lines($f(server.log)) | echo -a Loading variable }

  if (%mi.l > $calc($lines($f(server.log)) + 1)) { set %mi.l $lines($f(server.log)) | echo -a Re-loading variable } 
  ;;Mirc 7.1 made the above line basically: >= when it was only supposed to be > so I added one to the line

  if ($lines($f(server.log)) && %mi.l <= $lines($f(server.log))) { 
    ;;Check if there is that many lines so mirc 7.1 doesnt create an error
    if (*:*:* * says: * iswm $read($f(server.log),%mi.l)) {
      msg %mi.chan $+(10<,$gettok($v2,2,32),10>) $gettok($v2,4-,32)
    }
    elseif (*:*:*  /* logged in as * iswm $read($f(server.log),%mi.l)) {
      msg %mi.chan 10 $+ $gettok($v2,6,32) has just joined the server.
    }
    elseif (*:*:* * */* lost connection suddenly.* iswm $read($f(server.log),%mi.l)) {
      msg %mi.chan 10 $+ $gettok($v2,2,32) disconnected from the server.

    }

    ;;I would use regex however mirc 7.1 is epically slow with text files already so meh
    inc %mi.l 
    .timer.check 1 1 checkf
  }
  else {
    .timer.check 1 2 checkf
  }
