Is this run by VCOM? If so I would like to get involved with updating the map pack, fixing bugs etc.

No.

This is my personal project. If you want to fix bugs then you are very welcome. Map selection is usually by popular opinion. I could do with someone active telling me whats working and whats not. Someone to fix maps that could be added would be a blessing.

Spider Blood and Kings Moves need to be removed as the colours are usually messed up or unfair.
Have you taken a look at the topic in general chat? Popular opinion seems to be we should have as many maps in the ladder as possible, all of the maps mentioned should be added.
