I made this addon a long time ago, but just forgot to upload it, so here it is.
Simple Vote:
This addon adds in 3 small commands which add custom votes/ready checks
/ready [Message] This sends a ready check with a custom message. The result of the check will be sent to you in the chat.
/vote [Message] This sends a simple majority vote in the form of a ready check. When more than 50% of the group says yes, the check will pass and you will be notified. Due to Zos' limits, whenever anyone says no, the vote will fail.
/supervote [Message] This sends a supermajority vote in the form of a ready check. I don't actually know what the cutoff is for a supermajority, but it's an option in the API, so I wrote it in. Due to Zos' limits, whenever anyone says no, the vote will fail.
I might add more features later, but it's not a high priority.
