probably some, but none that I could identify.
disability
I am in a wheelchair and I was wondering about others on the site so we can play a game & chat about our likenesses. That's all
I am a freelance journalist and I have have been assigned to write a cover story for Chess Life magazine about chess players (online, clubs, tournaments, etc.) with disabilities. We are interested in talking to any and all chess players who identify as having a disability, but are especially interested in speaking with "wounded warriors" with a serious interest in chess. If you are interested in speaking with me, and available to talk within the next couple of weeks, please send me a message at christenmccurdy (at) gmail (dot) com. Please feel free to send my contact information to anyone who might be interested.
If you need help, please contact our Help and Support team.

are there any wheelchair-bound players on this site?
