Regarding the remove all points, I believe you can do @editpoints@[all|-X]. Replace X with the number of points you are removing. It doesn't produce a chat message so you'll have to include a chat message in the command that you call this in. so for example you make a command called !removepoints and it takes a single argument, you would use it like "!removepoints 5". The command code would be "@target@ @pointsname@ have been removed from all users @editpoints@[all-@target@]"
