The best way I know to get others to use them is to show them how slow the non-lisp way of doing things works, then show them how fast the job goes when they use the new programs. Also, a good way for them to remember them is to create a menu for them. Toolbars are okay, but my personal opinion on them is that, no matter how hard you try to setup the perfect toolbar, some brainiac will move tools from one menu to another and will be bugging you the next time they open cad as to which smiley they're supposed to use. Create a pull-down menu and let them create their own toolbars.
