Well, hypothetically, I have...
91 members besides myself joined during my leadership... but some did it without real prompting, though many were still attracted by stuff I did. Along with others of course, and others invited their fair share too. But at least the initial founders, I know I recruited all five Co-Alphas and was a driving force in the integration of certain others over time. I guess the biggest times for my personal recruiting were the first several weeks and the heat of the Wolves-Bears Wars.
I'd say I probably had a direct involvement in the recruitment of 20-40+ members, and indirect in several more. But of course, you mean starting now, so I'll get to that for ya.

We need to find a way to have that excitement and involvement we got around that war, but with more positive feelings.
