Perhaps the question we hear the most about Glassboard is, "if it's free and you don't do ads, then how do you make money?"

The answer is with a premium subscription, which is supported by new versions of the app that are now live in Google Play, the App Store and on the web.

For an overview of the goodies our premium version has to offer, head over to the Glassboard Blog. But I will give a shout-out to what has become my favorite premium feature: bookmarks.

At Sepia Labs, we use Glassboard to build Glassboard. Every feature, fix and improvement is discussed on Glassboard itself. Being able to bookmark messages and comments is a big help – bookmarks are my to-do list of things I need to act upon. I also bookmark photos I really like, as you can see in the screenshot below this post.

If you're a Glassboard customer and you want more out of it, I hope you'll sign up for Glassboard Premium. But even if you don't, be sure to get the latest version of the app because there are a lot of improvements for non-premium customers as well.

PS: We'll be adding some great new premium features over the next few months – there's much more to come!
