Project 'sign up' feature(s) - create volunteer list and enable group messaging

[BenBallingall]

Members are able to sign up to projects by emoji reacting to a project call in server and/or Projects Bot DM. Project Leads are able to send messages to signed up members via Discord bot - for information updates, group chat planning

I imagine something along the lines of:
-Member reacts to emoji
-Bot saves their Discord# to project in database
-Bot messages Project Lead to say a new member has signed up
-Project Lead can use a command to have Bot DM them with list of signed up members
-Project Lead can use a command to have Bot send out message to all signed up members

Personally, I like this - though I'd say it'd be kept for projects lead by Flux Vetted/Master Fluxer for the first run to limit spam.

Thoughts?

Without looking into specifics of how to implement this/documentation, I like it and would add this as you explained.
