Is there a requirement for initiation to join a gang? I found this on the web, I listed some of it below.
My gang has become somewhat infamous for its use of the third method. It's not strictly a requirement, but it certainly helps, and in any case I've yet to hear any complaints. - Initiation by cop
- Being jumped in or beat in
- Sexed in
- Jacked In
What's the minimum Foxpup merit I need to have received to be part of the club?
It varies depending on whether you're a merit source, the number of (other) merit sources you've had anilingual relations with, and what vibrational level I had you set at during said relations. Ask cryptohunter for details.
