David Hogg's ready for another major rally -- getting students nationwide to sign up for his political activism club.

We're told David and the March for Our Lives leaders will be launching a new platform for students to create school clubs and engage them in political activism. Here's how it'll go down -- students will be able to go on the MFOL's website and create a club for their school anywhere in the good ol' US of A.

From there ... students get support and help with﻿:

-- Letter-writing campaigns to lawmakers

-- Hosting town halls

-- Planning future marches (like March for Our Lives)

-- Starting voter registration drives

-- Supporting candidates who support the MFOL mission (either Democrat or Republican)

-- Helping students get on campaign trails
