Idea für %player% and %code% and %url%

[calgia]

Hello

I do not now each shortcode and would like to have a information for where %player% and the others could used. As well would i recommand to ad the possibility to vrote a warm welcome message like
Hello %player% Welcome on our Server. You have sucessfully authenticated!

I does not now if that is possible but i would like it.

EDIT:

A URL like goo.gl/asdf1234 would be nice, istat of www.google.com/long-url-from-chat-min-3-lines-long

Greatings,

calgia
