So far, folks have talked about why they, individually, can't or don't play in "This Day" events.
Those are good to hear, but generally whenever I'm running these events, there are at least 300-400 players in the Main Arena at the time who are thus available to play in the event.
How to I better reach those folks? How can I get more of them to try out "This Day"?
I already put posts about the event up in various areas of the message board starting about 1 month in advance, keeping the topic I start fresh. I announce in the Main Arena (via the CM announce tool) shortly before and slightly after I start the event, telling about it and asking folks to give it a try. I talk about "This Day" events occasionally in the Main Arena, working to recruit people into the events.
What I think that I need are more players working to spread the word and helping to recruit players (their pals, their squaddies, or just anyone who seems like he might be interested).
