Legendary Pokémon

I went to subscribe to a thread only to discover the option is no longer available. I haven't been receiving emails when someone posts on the the threads I'm subscribed to either.
What's wrong?

Indeed thread subscriptions are gone.
We've had trouble with activation emails not being sent for a while now, and the culprit was most likely subscription emails overflowing the daily email limit of the server.

I'm afraid you'll have to resort to using the new posts search. :/

Okay.
Thanks for letting me know!
