I’m managing few twitter accounts for my company and it would be difficult if i have to use multiple email accounts for multiple Twitter accounts. When you try to create a new account with a email id which is already associated with an existing Twitter account you will get the following error message  ”This email is already registered. Want to login or recover your password?”. Well, there is an easy way to overcome this issue if you have a gmail account. Here’s what you have to do:

- Gmail ignores dot (.)  in the username. So you could add variation to your username by adding a dot in between your username. All the emails send to these emails will be send to your actual emails. Ex: For the email id superstar99@gmail.com you can add a dot (.) and create more emails like superstar.99@gmail.com , super.star99@gmail.com , su.perstar99@gmail.com or super.star99@gmail.com and all the emails send to these ids will be send to superstar99@gmail.com .

- Likewise, Gmail also ignores anytext after “+”. So you can create more id’s by adding “+”. Ex: superstar99+Twitter@gmail.com, superstar99+Twitter2@gmail.com, superstar99+Twitter3@gmail.com etc anywhere in the username and all emails marked to these addresses will still reach your own Inbox.

Not only in Twitter, you could use the same trick in many other websites. Hope this helps.
