Unit bbs_SysOpChat;

(* some ideas for chat:

split chat additions:

- scroll half window instead of just the last line
- allow full arrow key movement in chat windows...
  kinda like a full screen editor...
- ctrl-k brings up a command menu, which has:
  OutFull file
  display file
  dos drop?  add mini-dos internal to mystic?
