Comment - Leave Comments on other player's characters with gifs which define how you see a relationship between those characters going! Don't shy away from crack ships or ridiculous things! And, it doesn't have to be a romantic relationship - it could be platonic, family-orientated, etc (specify in the Subject line if you want to!)
Profit - All of this information is OOC knowledge only, but may be used by the scientists in future. As a bonus, If IC/OOC comments on any post exceed 5 comments (each), we'll let you count it as activity for that character this month. So some AU character reactions and interactions on this post is a good thing!
Remember: the survival of humanity depends on your contribution!
