SE.net invitation codes

I'd like an invitation code since I really wish to get into Social Engineering, and feel like if I was able to go on the forums; conversing with others and just learning tips on how to do it in general, that it would greatly improve my confidence in the area as well as allow me to actually do it 'correctly' by finding out which methods work better for me and potentially finding various unsaturated methods for it as well. Once I learn how to SE it'd be nice if I could share that knowledge and help people with it as well. I might be able to get a few things for my little siblings too that cost a pretty penny (PS4, PC, etc.) since I'm only 16 and don't really have that kind of funds except around the holidays.
