Quite frankly, I don't want to set limits at this point since I'd consider the event successful if we even have 20 people attending.
I'm sure we can come up with better name tags than last year. We can make a 'Toronto Prop Party 2012' template and find some plastic sleeves. This can definitely be worked on.
Honestly, I'm not that keen on paying for multiple printed ads at this point, however, I can see an advantage to placing 1 ad soon, then another 1-2 ads just 2 weeks prior to the event. Again, I don't want to gamble on how many extra people paid ads may attract because that research can get expensive. Even if I place an ad in 'Now' magazine or 'The Grid', the quickest link would be the Facebook page, which was the primary reason I setup it up Facebook.
I'm open to all suggestions and ideas. I'm trying to spread the word as 'freely' as possible(no pun intended). I'm a member of SciFiHero and have been plugging it there. I started a thread on 'theDentedHelmet' as well.
