is there a certain website or list that is popular with cosplayers going to Gen Con?  I'd like to be able to meet up with folks and just chat.  Going as Pathfinder characters with my spouse so far and he'll be helping run 7th Sea so he'll be in piratical stuff we have left over from decades in the SCA. 

The Gen Con Indy Facebook group gets a fair bit of cosplay discussion.
 

thank you!
