how can i put a message that appears for anyone who joins the server ? Write: /motd what you want it to say. Example: /motd Welcome to my server, have fun.
how can i choose amount of tc to be the minimum of betting ? Write: /minbet tcamount. Example: /minbet 500. Then people can only bet 500 or higher.
how can i color the name of the server ? You can colour all the text you make, by writing: ^twonumbers textyouwanttosayincolours. Example: ^02 Dicks. Then there should appear a red text saying "Dicks". You can combine every two numbers you want. 58, 85, 99, 36, 71, 14 and so on. If you want the server name to appear in colours then you will have to combine the two commands. /desc ^14 Betting-in-here! (Be aware that you cannot make spaces in the server name) The server name should appear like this:
Betting-in-here
