3.9.4.8+: New Features:

• Verified to work with 1.6.4
• Admins won't activate signs when left clicking
• Better sign messages

In version 3.9.4.8 I added a new configurable message. That means that the message.yml will be changed. Usually this process is automatic... but, if it isnt and you get players getting a "null" message add the following into the messages.yml system: section. And change the version to 1.6.3 if its not

version: 1.6.3

and in the system section

system:
    match_starts_immediately: '&eMatch starts immediately when &6%s&e more players join. &6%s/%s'
