If you're curious about a particular author, sometimes it's awkward to read their early posts. So I added a command to help with that:
$first <account> [+offset]
For example, say we want to take a peek at papa-pepper's very first post:
$first papa-pepper
This will retrieve the very first post by the author specified.
You can also ask for an offset:
$first papa-pepper 100
Really, this is the first + 100th post.
