Seeing Zany Serendipity's request to have the calendar reflect via banner when Zilloween is happening made me remember to post this idea.
May we consider having an "opt-in" email request in our preferences that would send us an email letting us know one game day before things like Pii Day and Zilloween start? Along the same lines, would it be feasible to send us an email when a new feat is opened so that if we're not in-game we'll have a chance to log in while it's still live?
