step 1:
Sense It's only one address, and a very specific one at that you are trying to ignore, use the following:
on *:JOIN:#idlerpg:{ if (zz_SophieB == $nick || *!*SophieB@li183-18.members.linode.com iswm $fulladdress) { halt } }
on *:QUIT:{ if ($nick ison #idlerpg) && (zz_SophieB == $nick || *!*SophieB@li183-18.members.linode.com iswm $fulladdress) { halt } }
2) in mIRC, hold the [alt] key and press [r]
3) Click "file", then click "new"
4) Paste the code in the empty text box
5) click "file"
6) click "order"
7) Move that scrip to the very top of the list
Sense the script is the first to trigger, and it halts the events, it should stop all other events of triggering for it as well....I think
