Usage: INVITE <nick> #<#channel>
Usage: INVITE #<#channel>
This command is used to invite people to join a channel. The server will send a message to the user, inviting them to join and allowing them to enter through CMODE +i and other restrictive channel modes. This is the only way to let someone into a channel that is +i, if they do not have at least UOP access in it.
If only a channel is given as parameter, then you invite yourself into that channel. This requires access to the channel (see ACCESS for details) and is mostly useful when a channel mode or ban list entry prevents you from joining normally.
/invite residue #support
/invite #island
In general, if you have an invite only channel, this is how you will let people join. You generally only want to invite people you know, because random invites are usually considered rude or even synonymous to spamming.
Note: the syntax with only one channel parameter to invite yourself replaces the service command /CS INVITE.
