If you’re a regular user you’ll have already noticed by now, but in case you hadn’t – del.icio.us inbox is back! (via WaxyLinks).

If you’ve not used the inbox functionality before, it’s basically a mini-aggregator for del.icio.us, so that when you’re viewing another user’s del.icio.us bookmarks (say, mine), you can click “subscribe” at the top of the page, and then all of that user’s bookmarks will appear in your inbox (see my inbox for an example). This makes it much easier to manage subscriptions to multiple del.icio.us accounts.

Not only that, but you can also subscribe to a user’s tags and to global tags, so for example you could subscribe to my bookmarks about jabber, or everyone’s! Marvellous!
