poll

Creates a new Poll for people to vote on. Has very configurable options.

Specifying a Poll that has no options will add the 👍 and 👎 reactions for people to use:

!butler poll Is the sky blue?

You can specify up to 10 options on new lines:

!butler poll Which is your favourite animal?
Dog
Cat
Mouse

The above will give each option a letter of the alphabet, e.g. A, B and C, for the reactions. If you want to specify your own emojis for each option, you can do so:

!butler poll Which is your favourite animal?
🐶) Dog
🐱) Cat
🐭) Mouse

You can also negate the text altogether and use just emojis:

!butler poll Which is your favourite animal?
🐶
🐱
🐭

It is also possible to mix-and-max these options:

!butler poll Which is your favourite animal?
Dog
🐱) Cat
🐭

Note: Whilst you can use custom emojis, please only use custom emojis from the server you're posting the poll in, otherwise it's unlikely the Bot will find them.

prefix

Changes the Bot Prefix for this Server.

Note: Only the Server Owner can do this.

For example, using the following:

!butler prefix .

Would mean that instead of !butler price btc you would use .price btc.

If you want to end your prefix with a blank space (Such as the default !butler prefix), replace the space with [space]. E.g.:

!butler prefix !butler[space]
