If you're logged in, you will see a Tools button near the top of your SmugMug pages. Click it and then choose Go to Control Panel under "My Account." Or, click the Control Panel button on your homepage.
The Control Panel looks like this:

Your Control Panel is for your eyes only. No one else can see it unless they log in as you. If you are a Power or Standard user, you'll see five tabs. Professional users see a sixth tab, "Pros".
Each tab holds useful stuff:
News
Shown above, this tab includes SmugNews, which is updated frequently and gives you the highlights from the latest Release Notes. The Partners section lists companies who offer great products we love to share.
Stats
Your Stats tab is where uploads are tracked. Click "upload log" to review the last month of photos you've added along with any upload errors.
Photo views are reported and the "statistics" link will give you the nitty gritty hits on each image size in each gallery. Tell me more.
This is also the place to moderate and delete comments. Click the "view" links to get more details and enable/disable comment approval. More comment help.
If you use Share emails, all invitations that you've sent to view your photos are tracked here.
Referred anyone? You'll see your referral credits rack up here. Click "details" on the Ready to spend line and see the breakdown. What's a referral?
Settings
This is the place. We've organized all your goodies into three basic areas for easy navigation.
You can change and update your account level, SmugMug nickname, billing information, and email address right here.
If you're a Professional or Power subscriber, you can also add a domain but make sure you've set up the domain properly, first.
The Security section contains all of the site-wide security features, such as passwords and SmugIslands settings. If you want to add photos via email, create an email password. If you're a Professional subscriber, you can change your assistant login password, too.
Site-wide Features take care of everything else. Don't want to be bugged by news emails or comment notifications? Set your email alerts here.
You can Allow Collecting of your photos into other Smuggers' galleries, but if you prefer to keep them to yourself, simply disable that here. More details.
Visitors to your SmugMug site using an iPhone get a special view that is optimized for their browsing, but you can turn this feature off if you wish. You can also disable Feeds for your SmugMug site, but note that this will break certain cool features such as maps and embeddable badges or slideshows.
We automatically extract keywords from the descriptive filenames of your photos, but you can disable Filename Keywording here, too.
You'll also see a spot to enter a Homepage Meta Description. Choosing your words carefully can help increase your site's relevancy in searches. More on Search Engine Optimization.
You can also create or visit your SmugVault to manage your archives.
Color correction is an option only Power and Standard users will see on this page (Pros see it in their Pro pricing). For the print lab that Power and Standard subscribers go through, color correction is automated and described here.
Pros
If you have a Pro SmugMug account and you've set custom prices, we'll track print orders where you made a profit. Click "sales history" to see a breakdown of every item on every order.
Submit and review your tax and payment information so that we can pay you.
Pros who wish to collect sales tax on their orders can configure this using the Sales Tax Tool.
