CatMan is correct. Having used MyBB before and having read and understood its code, I can say for certain that notifications do not get queued while you are considered "active" (usually within "the last 5-15 mins" but is configurable). I don't know what Shannon/Andrew/Ben have set it to for this board, but I get emails within 10 or 15 mins of "inactivity" (anything past the above 5-15 min mark is considered "inactive"), and if I remember correctly the queuing of emails is run every X mins (e.g. checks every 10-15 mins if there's a "new post" and runs the list of subscribers and notifies them if they're "inactive").
