That would be one solution but I was thinking to proceed with only your agreement. You were the main contributor to these files. Honghui added a few descriptions. Other developers added only compatibles. Since we cannot reach Honghui, I would assume that your agreement (Sign-off) is enough. Best regards, Krzysztof
