I can get the attention of the rest of the site, and see how many people are interested.
Oh, it's no problem, the site has about 500 unique users per day, so if we manage to get enough people's attention we could reach 50 people! It's all about seeing what people would like to have on a t-shirt.
As far as I'm concerned, the shirts don't have to be MLPchan related, using MLPchan /fan/ as the hub for this will be good enough. I'll see with the rest of the staff, and from there we'll see with the userbase what they'd like to have on the shirts. Will keep you updated!
Do you happen to be on Skype/steam, in case I need any info fast?
