I use the welcome panel plugin which has /help  to display commands etc
i was using advertmessages to display commands also,  this meant constant text being displayed,
with this if someone types  help  or command, then they get an automated reply and explanation
this is literally perfect for example in my build server, If someone types how do i fly  or is there no clip then it triggers the automated reply

simply type   /fly  to fly like superman
This is a simple but very effective plugin and comes highly recommended!

Does exactly what it says. Using it for info/triggers like "wipe", "purge", "commands".

Love a plugin that loads itself without too much fuss! Simple and easy, thank you so much. Great for new players that need info since we have many solo's who dont chat much. 10 stars!
