IRC Options
Show short joins/parts
Checking this option makes mIRC display the join and part messages in a different, more compact format.
Show user addresses
Whenever a user joins/parts/quits/is kicked/etc. from a channel, you can choose to see their address by selecting this option.
Show nicks on join
Displays channel nicknames in the status window when you first join a channel.
Flash on...
These switches set the default flash option for any new channel or query messages that open.
Skip MOTD on connect
This makes mIRC hide any MOTD information which the server sends you when you first connect to it.
Hide ping? pong! event
This hides the Ping? Pong! messages that mIRC shows in the status window whenever a server sends pings to your mIRC to check whether the connection is still active.
Cancel away on message
If you set yourself as away, using /away <text>, selecting this option cancels the away option automatically if you send a message to a channel or a query/chat window.
