I would like to find some tutorials to refresh my memory and use Hootsuite more efficiently.

Thanks for commenting, Lisa! Hootsuite has lots of great videos on both of our Youtube channels, Hootsuite and Hootsuite Labs. If you're looking to refresh your skills to use Hootsuite more efficiently, I'd recommend checking out the "Getting Started with Hootsuite" playlist videos (http://ow.ly/uiyv50JagQy) - or just google 'Hootsuite Getting Started videos' and you'll be on your way! Hope this helps!
