I have no idea what a Ray ID is.

To replicate, the relatively simple instructions for setting up the ifttt.com (create a free account there if you don't already have one) recipe are given here in post #295:

"We got a new subforum -- I'm so happy/I'm so sad" DISCUSSION THREAD

I thought it was discussed elsewhere, but I'm not sure where that was. Anyway it's pretty easy, and those are the correct instructions.

The problem seems to be that either FT or whatever thing they have in front of FT (attack filtering, etc, like cloudfare) has probably blacklisted ifttt.com's RSS requests. That's a good clue to figuring out where that's happening.
