I see what he's getting at here... I had the same issue when I was trying to write a Newbie Guide.
With the old way, one could simply add a dummy command with cedit that referenced to the do_chan code. For instance:
cedit nc create do_newbiechat
cedit nc level 1
cedit save cmdtable
Doing this would in affect create an alias for the newbiechat command, making it easier on newbies.
If AFKMud does not have a way to do this, I think I'm going to try and expand the player's personal alias code to encompass a global alias type thing that an immortal can set.
For now, the only thing I've been able to do is use this issue in teaching newbies how to create an alias. (I have them type: alias nc newbiechat)
Hope that clears things up.
