Expert Witnesses

Note that this is a list of volunteer experts. Don't add anyone to this list besides yourself, and be polite and courteous to these volunteers. They don't have to help you and are providing their services out of the goodness of their hearts.


  • You must have either a degree, significant professional experience (meaning at least several years), or have in-depth academic knowledge in the field. If you are merely a hobbyist or have some passing interest in a subject, you should not consider yourself a subject matter expert.
  • You must be regularly available via forums and/or IRC. If people can't easily get a hold of you, then that doesn't really help. If your IRC nickname is different from your site name, please list that as well. You will be considered inactive if absent from your preferred contact method for over one year.
  • You must be willing to help others with your subject matter expertise. This isn't a bragging contest or talent show, this is an effort to get people in contact with experts who can help them with technical details.
  • Please defer to active contributors. Even if you are a valid subject matter expert, knowing how to apply that knowledge to writing for the SCP community is critical in separating actually interesting information from unnecessary fluff. If you have not successfully contributed to the SCP Wiki in the form of SCP articles, tales, or other non-collaborative literature, then please defer to those who have.

To add yourself alphabetically to the list in the appropriate category/ies, please insert the following code with your professional experience/credentials:


If you want to make yourself available for reference on stuff you're a hobbyist at, feel free to list that in the comments on the thread named "Non-profession Helpers". If you believe a listed user has become inactive, please contact a staff member with the relevant information.
