Chat moves very quickly at times and it can be difficult for people to read and respond to what you have said. If no one responds right away, wait a few minutes and then say it again. You want to wait a couple of minutes so that you don’t spam chat.
Remember that people are more likely to respond to friendly words than angry or negative ones. For example, try saying “does anyone want to go mining?” instead of “no one is my friend D:”
If you need help from a staff member simply use /helpme why you need help and a staff member will respond to you as soon as possible.
