Easiest way to do that would be a simple mIRC script looking out for announces.
In remotes stick
"on 1:TEXT:*[section]*testing123*:#:/msg $me $nick said $1- in $chan"
then everytime someone says the matching text you will pm yourself with who said it, exactly what they said, and which channel it was said in. If using timestamps also get when said so can read back in channel
ie, from a test i did:
[22:06] <*****> EwarWoo said [test] - something.testing123 in #testing123.
You just check you PM's to yourself to see all the matched releases.
