TweetDeck back up after going offline to fix security issue

TweetDeck, a social media dashboard tool used to manage and post to Twitter accounts, has taken its service offline to address a security issue, but users should still take steps to protect themselves.

TweetDeck users should log out of the service by going to twitter.com, clicking the gear in the top right corner, clicking "Settings," then clicking "Apps" in the left-hand navigation bar, and revoking access to TweetDeck. Users should stay logged off until hearing otherwise from TweetDeck.

Updated at 11:03 a.m.: TweetDeck is back up.
