You can use Twitter to update Odadeo, and vice versa. Here's how:
If you are pledging to "Go swimming more often" and it is tagged 'swimming', then sending this message to Twitter will update your progress towards that pledge, without you having to visit the site.
Pipping is updated every five minutes, so there will be a short delay after you send the message.
If you update your profile page status (the big green speech bubble) and you have set your Twitter username and password in your profile this will also update Twitter for you.
It means you can update more than one Twitter account from Odadeo, so you could have a Twitter account for each of your kids (with updates protected, we'd advise) so you can use Odadeo to update them all once in a while. In future it means that more than one person can update the same Twitter account too.
