We don't have many regular AutoLISP users on LispForum. We do get a stream of users asking questions.
Here are some other forums where you are more likely to get good help.
* Autodesk.com: Visual LISP, AutoLISP and General Customization
* AUGI.com: AutoLISP forum
* CADTutor.net: AutoLISP, Visual LISP & DCL
