If you've ever wanted both an easier way to constantly keep up-to-date with the latest from your Multiply network and a dead-simple way to post new content, it sounds like you want the brand new
Multiply Toolbar.
Click that link; it's available now!

If the mention of the toolbar causes you to feel a strange sense of déjà vu, it might have something to do with the
toolbar preview we showed you a little while back. Or perhaps, if you're in the MUDS group (yay!), you may already be using it, thanks to the
sneak preview we posted there late last week.
One particularly nice feature is the integrated drag-and-drop photo uploader. Click the "Post" button followed by "Photos" and simply drag your photos onto the upload box -- no extra messy browser plugins needed!
As you probably already know, the toolbar works with Firefox and Internet Explorer browsers, so there's no reason to not give it a try.
