1-B Give them time to rezz and get into the club. Then greet.
2-B short gestures are good, long ones people tend to ignore and not read anyway, waist of space in chat.
3-B Chat should be the same as everyone else, notices can go either way, but why not just normal. I dont see the point.
4-A Say good things about the DJ and host, but same thing over and over has no real meaning to it and its ingored.
5-C No one likes to be presured to Tip over and over again. Adv stay in a club is 27 mins in most cases, Once every 30 mins is sufficent.
6-B Most have notices turned off, so keep it short and simple for those that have them on, or they will turn them off.
These are my opinions as a club owner.
