welcome.patch

   1 Add welcome message functionality.
   2
   3 client commands:
   4 user:
   5 /WELCOME
   6 shows welcome messages set, same is shown on connect
   7
   8 oper:
   9 /WELCOME [<target>] [[!]<name> :<message>]
  10 to view welcome messages from a remote server
  11 to set a local welcome message on this server or a remote server
  12 set a global welcome message (target *)
  13 the ! prefix makes the server annouce the welcome message to its clients when setting
  14
  15 server:
  16 :<source> WE <target> [[!]<name> <timestamp> <who> :<text>]
  17 who is who set the message, the server puts in the opername when a client sets it.
  18 :<name> is a number 1 to WELCOME_MAX_ENTRIES - currently set at 10 (should be more than we ever need)
  19 that means there is room for 10 local and 10 global entries
  20
  21 STATS W/welcome (/STATS w/userload made case sensitive)
  22 :server 230 nick W Name Target Who Timestamp :Message
  23 :server 227 nick W 1 * opername 1233072583 :Latest news: testing this welcome patch :)
  24 :server 227 nick W 2 * opername 1233072583 :
  25 :server 227 nick W 1 servername opername 1233072590 :This is a test server, expect restarts.
  26 :server 219 nick W :End of /STATS report
  27
  28 listing welcomes or on connect:
  29 :server NOTICE nick :[QuakeNet] Latest news: testing this welcome patch :)
  30 :server NOTICE nick :[server] This is a test server, expect restarts.
  31
  32 announcement is done by a notice by the local server to $* with the same message
  33 format as for listing welcome messages.
  34 :server NOTICE $* :[QuakeNet] Latest news: testing this welcome patch :)
  35 :server NOTICE $* :[server] This is a test server, expect restarts.
