Code:
ON *:JOIN:#: {
  if ($nick == $me) {
    echo -ta User levels are: $nick($active,0,o) Ops, $nick($active,0,v) Voices, $nick($active,0,h) Halfops, $nick($active,0,u) Userops, $nick($active,0,r) Normal users, $nick($active,0) Total users, $ibl($active,0) Bans.
  }
}


Not tested in the ON JOIN environment but in theory should work. Just edit out the mode types that don't apply to your network. :grin;

I do know that if you have access to the channel this won't be shown here unless you run the /echo as an alias.

Code:
EG ON *:JOIN:#: {
  if ($nick == $me) {
    .timer 1 1 cumodes
  }
}


...then

Code:
alias cumodes {
  echo -ta User levels are: $nick($active,0,o) Ops, $nick($active,0,v) Voices, $nick($active,0,h) Halfops, $nick($active,0,u) Userops, $nick($active,0,r) Normal users, $nick($active,0) Total users, $ibl($active,0) Bans.
}
