You think this, or parts of this, will work with TwitchAlerts?

Technically, Editing it just a little bit, It should work.

I took the "alias CheckNewDonations" and tweaked it a little so it compares to the API page from TwitchAlerts.

Thats the only part i use and i have the following when i connect mIRC to the channel:
on 1:CONNECT:#channelname {
CheckNewDonations
}

(I'm not the best at working in mIRC.)
