So I am trying to make a loner club, just so I can get the effects and do the aspiration on my loner vampire , but as she is in a club by herself she can't start a club gathering, I have gone into the club tuning xml but can't find anything to do with required members for gatherings.

Any help would be appreciated

Please and thank you, Dezzter

Well, 6 years later I am looking at this problem again, I found a tuner that seemed promising in clubGatheringSituation that says <T n="_minimum_number_of_sims">2</T> and changed it to 1 but still no luck.
