Ask HN: How to save old stories on HN?

I often bookmark a few HN articles I want to read that I don't have time to read at the time.

When I finally get around to reading them, it may be 30+ days later. I've found that HN doesn't allow old articles to be saved (upvoted).

I can understand they don't want someone going through and up or downvoting old articles; however, the fact that the upvote button doubles as "saved stories" creates a problem for me, as I now want to save that article, but have no way to do so.

So my option is to either bookmark the article, or email it to myself, or something along those lines.

Long ago, I'd use a service such as del.icio.us for saving articles, but no longer have that option.

Anyone else experience the same issue and have a decent solution?
