Have you ever tried to signup for a second Twitter account using an email address that has already been used? Unfortunately, Twitter tries to tell you that your email is already registered. Many GroupTweet users run into this problem when trying to register their new Group Twitter Account. Don’t worry the solution is easy. The only thing you need is a Gmail address.
All you need to do is to enter “+something” AFTER your Gmail username and BEFORE the “@gmail.com.” Gmail allows you to use “+” signs to create email aliases. Gmail just ignores anything after the “+” sign and delivers the email directly to your normal Gmail account. See the picture below:
In this case, I’ve simply added “+grouptweet” to my email and now Twitter says my email is ok! In this example, Twitter emails sent to craft.ryan+grouptweet[at]gmail.com will be sent just like normal to my everyday gmail account, craft.ryan[at]gmail.com.
Simple as that!
