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 | |
