Well there is no point having a dat with missing CRC's in my opinion so this would need to be gathered before anything could be done. Also one issue would be how do we know the CRC's people are submitting are correct? It seems like a hell of alot of work and would take alot of time that unfortunately I, nor the staff members, have.
Feel free to post your CRC's if you like but someone will need to take control of this and manage the submitted crcs into one large .csv file whilst also checking it is valid information. Who will do this? I'll leave that to you to decide.
I would love to help more but unfortunately my spare time is non-existent at the moment.
