Back in October, 2013, Twitter launched a feature that allowed folks to send direct messages to anyone on the social network, provided that the option was enabled inside of settings. It lasted about a month before Twitter reverted the policy back to only allowing users who follow one another to DM. Now, in an effort to take on other popular chat apps, the feature is back.

“We continue to invest in our private channel to lay the foundation for a powerful and engaging messaging experience,” Twitter said, according to CNET. It’s the second major change to the company’s DM feature, which recently gained support for group messaging, too. It should still be optional for folks who prefer to use Twitter more privately.

CNET said the feature will soon hit Twitter for Android and iOS, as well as the Web version of the social network.
