You can also script your own tips to pop up as desired.
You can read about it at
/help /tip
/help $tip
A basic example would be something like this:
on *:text:*:#: {
var %nicks USER1 USER2 USER3
if ($istok(%nicks,$nick,32)) noop $tip(Message,$nick - #,$1-)
}
This would then give you a tip for whenever a user you added to a list says something in any channel.
