Why?

I'd like to send players specific messages and/or commands when they boost the discord.

What and How?

When a player boosts the discord, it should fire a PlayerBoostGuildEvent or something along the lines of that. I suppose the plugin could have an option in the config to run events/messages, but from what I could see the only thing that exists is the LP context.

Are there alternatives?

LP Context, which is not ideal for my usecase.

Checks

• I have used the search at least once to check if my idea has already been suggested and perhaps already implemented.

Anything else

I think that's all!

As Vankka said, you can already hook into JDA's GuildMemberUpdateBoostTimeEvent event if you wanted to, so having an event in DiscordSRV would be redundant. Won't be happening.

If you'd like to send out a message when someone boosts, you can do so through alerts as shown on the wiki

There's already a JDA event for this, GuildMemberUpdateBoostTimeEvent
