No. The book-keeping wasn't thorough enough to track that figure. However, my sister, who spent most of her time working registration, estimated around 200. We didn't even get the badges numbered, so the best anyone can come up with is a ballpark figure. However, based on the number of accounts registered on the MEW Forums, compared with the ratio of Kumoricon Forum accounts to actual attendance, I'd estimate around 350 people attended the convention between staff and attendees. It's not a definite figure; it's only real supporting detail is one ratio.
I think that verbal advertising will be important to MEW 2009's success. Since our audience is largely literary, we'll probably be producing Bookmarks again. If you're looking to build MEW, talk to me, Admin, Verdant Hero, Akio Legend, Lady Savant, or Kitsune about getting some bookmarks, then just hang out in the Sci-Fi/Fantasy/Manga sections of Powell's, Borders, or Barnes and Noble and just chat with people about the con, then give them a bookmark. A sample conversation might go like such.
"So are you a fan of [genre]?"
"Yeah."
"Have you heard about MEW Con?"
"No, what's that?"
"It's a convention held in the Portland/Vancouver area on New Year's with open gaming, live concerts, exhibitors, panels, dances, and all other neat things. It's kind of like Kumoricon and Sakuracon if you've heard of those, but smaller, with more inclusion of Sci-Fi and Fantasy."
"Sounds cool, maybe I'll check it out."
"Actually, I've got some bookmarks for the con. How about I give you one. It's got the website, date, location, and details on the back, and if you're not interested in the con, it's still a free bookmark."
"Okay, thanks!"
"See you there!"
