The Old method works best
1.choose your server, choose any channel
2.go into your inventory
3.hit F11, until it pops up the window
4.click ready, then tick the stuff u want ( if u have the item)
5.go back to server selection
6.enter the server, then while in channel window untick ready and hit F11 to close window, then choose the channel you want to play in
Good luck, have a nice day
