The day switch led to me forgetting. My excuse lol
Drew and I turned up to the original one though.
I recommend asking people for their reasons why they don't take part.
During the christmas period everyone has new toys and there is generally more family time. This is partially why I didn't partake in the events.
Since getting kicked I don't see much value in collecting guild items that I won't get to use. Which is why I only turned up for the previous event 5's date.
Other people probably have their own reasons. XD e.g.Life
Ask them or use survey monkey to create an an anonymous questionnaire if you want to be fancy. XD
