It is very simple, you will simply get the code from your Webull referral link and your Robinhood referral link. Simply paste it on any Project Bull Run link. There is a fixed structure:

Example Webull Link: 
https://act.webull.com/mo/rscWA1qapd9/qxj/inviteUs/

Example Robinhood Link: 
https://join.robinhood.com/nickf38

Your Adjusted Link: https://projectbullrun.com/?webull=rscWA1qapd9&rhood=nickf38

If you want to tell your friends about a specific page, just copy the URL and add the extension 

?webull=rscWA1qapd9&rhood=nickf38 

with your adjust referral code, make sure to copy your code.

Every WeBull and Robinhood link or images will adjust to your actual referral link.
