The new event scheduler is cool. I think it needs a bit more like a timezone conversion table
That aside, whenever an event is scheduled, it would be nice to directly communicate this to the entire playerbase as best as possible.
This can be done by;
(a) Auto private message to all players, which will hopefully send them a 'you have a message' note to the email they signed up to forums with
(b) Requesting directly an email address via pm from players who would like to be kept up to date
Most of us use smartphones now, and get email dings on those phones, so it's a great way to stay in touch with what's going on and get people in, so useful for lots of communication reasons not just informing of events.
