"Bringing a thread back from "the dead." If a thread hasn't been posted in within the last 45 days, don't reply to it. Start a new topic, if you want to discuss the subject (you are welcome to link to the old thread). If you think it would be better to resurrect an old thread, PM a moderator for that subforum and wait for approval. The original poster of a creation in Homebrew (and only that poster) may revive a creation beyond the 45 day threshold without prior Moderator approval."

When a thread comes back to life and there have been several days of discussion, sometimes I join the revived thread (because apparently the mods have approved this one) only to have a mod show up eventually and yell at everyone (because no one approved).

How are we supposed to know if someone PM'ed a mod before reopening a thread?
