You'll want to visit tacktracker.com/cloud for many reasons:
There are two ways races get published to the cloud:

Typically Regattas are published by clubs and associations - whilst home pages are published by individuals or anyone who wishes to publish a race to their account. Races are published using the TackTracker applications downloaded from the download page. A Race Editor license is also needed
To watch a race, click the button in the race list. Races are played in the TackTracker Web player in the main part of the window. If you don't see the player, it may be that you need to install the latest Silverlight plugin from Microsoft, or your browser does not support Silverlight.
Silverlight is not supported on mobile browsers such as Safari on the iPhone or iPad. But there is a great alternative: download the free TackTracker Player for iPhone and iPad from the Apple App Store.

TackTracker lets you navigate the home pages in two ways:
A home page presents races published by the owner of the page. The owner has the option of publishing races publically for anyone to view, or privately to his or her list of friends. If you are a friend, you must login to your account to see the private races.
Your first step is to create yourself an account on the cloud. Do this at tacktracker.com/cloud/auth/register.
To manage your home page, you first need to Login to your TackTracker Cloud account. Once logged in, you can visit your home page and edit or delete your races and manage your list of friends.
When you edit a race, you can change:
If you have live trackers and login to the TackTracker Cloud, you will see an additional Trackers tab appear:
On this page your live trackers will be listed along with the current status of each tracker. If any of your trackers is currently active, you can click on it to see the trackers current location on the map. If any other TackTracker trackers are in the vicinity that you have access to, you will see their location and tracks too. You will have access to any tracks publically recorded or recorded "friends only" when you are a nominated friend.
We've seen above how you can specify that a race is visible only to your nominated list of friends. To manage your list of friends, click the button in the home page header. This will expose your list of friends. You can delete entries from this list, or add a friend by typing the friends TackTracker username in the "Find user" search box above. The add friends button will add the specified user to your list.
Click the Setup icon at the top right of the cloud window to go to your setup page. This page has three tabs:
