anonymous queries

Some CQL team members are also endgame tournament judges. If you are an endgame composer searching for theme anticipations of a theme you want to keep anonymous, indicate that fact in your email without disclosing the theme. The email will be forwarded to a developer who is not a tournament judge.

bug reports

For bug reports, indicate the CQL version number, platform, and exact CQL file used where applicable.
