At CrashForum.info we have created special groups for CDR Users/Analysts, Heavy Truck EDR users, and professional Accident Reconstructionists. These groups have access to specific forums that are private to these groups. If you would like to apply for membership in these groups, access the "User Control Panel" in the upper right portion of the page. Next, click on the "Usergroups" tab. Finally, select the group that you would like to join, make sure the dropdown box says "Join Selected" and then press submit. You will be asked to confirm your application and then you will be redirected back to the board index.
Behind the scenes, an email will be sent to the administrators, the moderators or group leaders for approval. Once someone approves your application, you will be added to the requested group and you will be able to access the restricted forums. You may apply for multiple group memberships, however if you are approved for the CDR or Heavy Vehicle Analyst/User group, you will also have access to the Accident Reconstructionist Information Exchange Forum.
