The best way is to help develop this Wiki. Add some material, e.g., some critique, or a new challenge problem, and sign it with a link it back to a home page for yourself with your contact information (so that we can invite you).
If you are not into contributing in this fashion, then send an email to

with a short description of your experience and what you hope to contribute to the workshop.
