You're correct that the EY forum doesn't have a specific moderator, so in cases such as what you propose, the job falls to one of the four Senior Moderators - Moderator2, Ocn Vw 1K, oliver2002, and Prospero. So when you hit the alert button (which is not just for inappropriate content, but also "housekeeping" issues like merging), I believe the alert will go to all four of those senior mods and one of them should hopefully be able to help with the merge.
