This number tells the client it sends a raw command.

 A raw command should always end with a pipe,
 or else it will be discarded.

$UserCommand 2 <context> <title>$<raw>|

 This number is exactly the same as above, 
 except that the command only should be used once per %[nick].
 This is to prevent you from kicking more then one user 
 at the time. So this is only good in the fillist and search window.
        

 The contexts content tells the client where to put the command.
 In Userlist, hubtab, search window or the filelist window.

• 1 = Hubtab - This is good for !topic,+rules that dosen´t need a nick argument.
• 2 = Userlist - This can be used for all commands.
• 4 = Search window
• 8 = Filelist window -Note- In order for this to work, 
      you need DC ++ 0.669 or newer.
        
• Combine the contexts 

 You can combine the contexts, so you get the command everywhere.
 Then you just count the numbers together like this. 1 + 2 = 3
 Userlist and Search window. 2 + 4 = 6
 Hubtab, Userlist, Search window. 1 + 2 + 4 = 7
