- If an item has been sent by the comment author to the top-level post owner to relay on
|

|
to the rest of the contacts on the top-level post, the top-level post owner should check
|
||
|
the author_signature, then create a parent_author_signature before relaying the comment on
|

|
- If an item has been relayed on by the top-level post owner, the contacts who receive it
|
||
|
check only the parent_author_signature. Basically, they trust that the top-level post
|
||
|
owner has already verified the authenticity of anything he/she sends out
|
||
|
- In either case, the signature that get checked is the signature created by the person
|

who sent the psuedo-salmon
