It’s all about the availability of usernames to new users. Yahoo has officially announced in a blog statement that it plans to close inactive user IDs, so those usernames will be available to new users. Just recall, if you had any Yahoo ID that sounded great and you haven’t used it for a while, then just login to that account before July 15th. If any of your Yahoo ID has been inactive for over 12 months just login now.
Here’s the Yahoo blog announcement
If you’re like me, you want a Yahoo! ID that’s short, sweet, and memorable like [email protected] instead of [email protected]. A Yahoo! ID is not only your email address, it also gives you access to content tailored to your interests – like sports scores for your favorite teams, weather in your hometown, and news that matters to you.
So, how are we making these Yahoo! IDs available? We’re freeing up IDs, that have been inactive for at least 12 months, by resetting them and giving them a fresh start. In mid July, anyone can have a shot at scoring the Yahoo! ID they want. In mid August, users who staked a claim on certain IDs can come to Yahoo! to discover which one they got.
