I put in a complaint about the vetoed trades being processed by CBS this morning. I had two of them go through in my other league after they had been voted down. And it happened in this league once that I know of last week. The support team could not figure it out so it was forwarded over to the programming department.
I'll keep you guys posted but in the mean time, don't count on the website to hold trades for commissioner approval. If no one notices they may go through.
