#1 You cannot edit the version reply of mIRC to have the 6.2 by Khaled to not SHOW up its permanent live with it. You can in theory add to it or you can have people change the ctcp trigger like dave was talking about on a example

CTCP *:VERSIONX:?:{ Notice $nick I am using blah blah by blah }

#2 On *:SNOTICE:*: The only thing is I can't test this but it would perhaps be easy to figure out the proper commands do something like this

On *:SNOTICE:*:{
if (whois on you isin $1-) { echo -a $1 $2 $3 $4 $5 }
}

this way it will echo val $1 up to 5 so you know which one is the nick and once you found that out

On *:SNOTICE:*:{
if (whois on you isin $1-) { msg WhicheverVALmatchesNick I am watching you }
}

Code:
if $reality > $fiction { set %sanity Sane }
Else { echo -a *voices* }
