the ! prefix makes the server annouce the welcome message to its clients when setting
server:
-<source> WE <target> [[!]<name> <timestamp> <who> :<text>]
+:<source> WE <target> [[!]<name> <timestamp> <who> :<text>]
who is who set the message, the server puts in the opername when a client sets it.
-<name> is a number 1 to WELCOME_MAX_ENTRIES - currently set at 10 (should be more than we ever need)
+:<name> is a number 1 to WELCOME_MAX_ENTRIES - currently set at 10 (should be more than we ever need)
that means there is room for 10 local and 10 global entries
-local entries are cleared from memory when unset, global entries are kept with no text for conflict resolving.
