There is category A:
I receive an interesting communique via message or wall - size is not a mitigating factor although you will struggle to meet this criteria if you do not have a decent amount
I receive an incredibly original communique via message or wall - same as above
I receive a long communique via message or wall - your efforts shall be rewarded even if I do not find what you have to say very interesting
I am feeling benevolent and send you a message first
