I'm not sure if this got answered in another thread, but I haven't been receiving any sort of email notifications from the boards at all for weeks now. My subscriptions are set to email me by default. Did email as a whole get turned off recently?
FWIW, I haven't noticed a consistent improvement in the site's responsiveness, and I do sort of miss getting email notifications that point to the exact reply posted the last time I hit a thread... but I'm confident in the mods. Whatever makes the site better for everybody.
