Forums mIRC Help Please help me in setting "paging"

Dear friend,
I am using mIRC 6.31 and despite looking at the help and Googling for this I feel totally lost. Can anyone help me please ?

Here is what I need. I often work on Photoshop with mIRC that will be hidden or have mIRC active while I do other stuff at home and would like the PC to alert me with a sound (possibly a different one of each) and/of lashing taskbar for the following:

a) Any text typed by my friend with a certain nickname (and if possible even if he/she changes the nick such as Nick|AFK )

b) Any typed text, from enyone, in a PM

c) Any time someone types my nickname in the chat window

Thank you so much for any help

Rob
