You're replying to OP. :)

The link is in reference to "I found scans of his section on archive.org, including the issue where he announces the contest, but I couldn't find my particular contribution".

I've always wondered why HN doesn't have an OP indicator. A blue name ( similar to the green name for new accounts ) or an asterisk, just something subtle, would do.

Perhaps they don't want to mark out the OP as "special" to the resulting conversation, but it would help make the situation here clearer.

A good compromise would be only marking their top-level comments. And/or doing this only for Show/Ask/Tell threads.

I'm sending this thread to the admins as a feature request.

Tampermonkey to the rescue!

Quick slaptogether. I'm decidedly mediocre at web so if anyone has improvements, please post them :)
