Rules

Capture the Record Rules:

Two teams, gold team and green team, these teams correspond to the colours of the records
Both teams are allocated spawn areas and a radius, in which the record can be placed and captured, each spawn area is automatically given a chest, called the team chest.
The team chest cannot be accessed until the game starts, it contains the record for that team
Creepers are disabled (optional)
Items cannot be brought to or from the game world (except to and from the nether)
Non ops cannot build before the game starts (unless given the ctr.world.allowedit permission)
You can't enter the nether with a record
You can't drop your record
You can't leave your spawn area with your record
When the game starts both teams have an pre allocated length of time to build defences, this is called the build time, during this:

PVP is disabled
You cannot enter the other teams spawn area
You cannot use chests within the spawn area of the other team
You cannot edit blocks inside the other teams spawn area
Chests can only be used above water level and within your spawn area, while holding a record, this prevents people hiding records far underground or very far away
If your record isn't in a chest in the spawn area when the time expires, you lose

After this time expires, both teams have a pre allocated length of time to capture the other team's record, this is called the capture time, during this:

PVP is enabled
Using the other team's record in a jukebox, which is in your spawn area, wins the game! (Or using the shared jukebox, this is up to you)
If the time elapses it's a draw
You can enter the other teams spawn, destroy blocks, place blocks, open chests etc
