Some of the NW guys do put parties together but they do often seem to get cancelled or be close to not going ahead due to lack of confirmed numbers, I believe the SGK / Antonia / Pure loving poison party that was scheduled for Wed of last week was 2 guys short.
Not sure about others but parties being mid week are a bit of a no go for me as i'm working, perhaps may be more interest at the weekend though this won't be an option for others
All the feedback and reviews from gangbangs that have happened has been top notch but it looks to be a complete pain for the guy trying to get everybody on board, bit like herding cats
